There are mere hours to go before tomorrow morning for the presidential# primaries.

On the Republican side,## former President Trump is seeking a sequel# to his runaway victory in the Iowa caucuse GEOFF BENNETT: And President Biden is the# prohibitive front-runner for the Democratic## Party's nomination and is expected to win the# most votes in New Hampsh name isn't on the ballot.

That's to adhere to# a rule by the Democratic National Committee.

Political correspondent Lisa Desjardins# is in New Hampshire and joins us now.

So, Lisa, this is an unusual# New Hampshire primary.

The Republican race is already down to two# candidates.

And President Biden's as we mentioned, isn't even on the# ballot.

How are the campaigns seeing it?

LISA DESJARDINS: This is the first primary# of the 2024 presidential election.

But the## Biden and Trump campaigns hope that it will# be essentially the end to the real contest.

With Chris Christie dropping out over# a week ago and with Ron DeSantis over## this weekend dropping out, suspending# his campaign, for the Trump campaign,## they want to make sure that Nikki Haley# does not get any momentum.

They want that## to end here.

For Biden, he wants to stop any# potential rebellion even before it He has challenges of his own making.

But,## essentially, what's happening here# fo r both parties, any chance to avoid# a Trump rematch has to happen here.

NIKKI HALEY (R), Presidential# Candidate: Thank you so much.

LISA DESJARDINS: She i NIKKI HALEY: That's the# sound of a two-person race.

(CHEERING AND APPLAUSE) LISA DESJARDINS: With Ron DeSantis out, former South Carolina Gove NIKKI HALEY: When you vote on Tuesday,# you're going to be making a decision,## do you want more of the same?

AUDIENCE: No!

about education and the debt, and conservative,# including blocking transgender girls from sports.

This is her most competitive state, but she# stumbled here last month in not naming slavery## as the cause of the Civil War.

Haley trails# Trump and needs voters like Steve Kesselring,## a Trump supporter until his 10-year-old daughter,# Hannah, asked to listen to other candidates.

They did again and again, New Hampshire-style.# The two became campaign trail celebrities.

HANNAH KESSELRING, Nikki Haley# Supporter: Eight Nikki Haley events,## three Chris Christie events# I have to.

He's been to four.

LISA DESJARDINS: And Steve became a Haley voter.

STEVE KESSELRING, Nikki Haley Supporter: she like the largest debt that -- of any sitting# president.

what do I want to leave for my daughter?# What do I want to do for her future?

LISA DESJARDINS: What Hannah wants is not Trump.

HANNAH KESSELRING: He's going to call# Chris Christie a to call Nikki a birdbrain.

I don't# want m LISA DESJARDINS: But from# throngs of Trump voters here: KAREN MACDONALD, Donald Trump# Supporter: I wil of that be LISA DESJARDINS: There is unmatched fervor# and crowd size, where he taunts Haley.

DONALD TRUMP, Former President of the United# States (R) and Current U.S. Presidential## LISA DESJARDINS: And where Trump,# who faces 91 felony counts,## argues he should be immune from most prosecution.

DONALD TRUMP: This isn't just me.# This is all presidents.

They have to be given immunity.

Otherwise,# they're go LISA DESJARDINS: Many believe# Trump's lies about the 2020 election,## but others we spoke with shrug that off and# say they see a strong man on FE BIE SALTS, Donald Trump Supporter:# Number one is immigration.

I came in## this country in the front door, not the back door.

BRANDON ALDRICH, Donald Trump# Supporter: I love the fact he is taking care of our border LISA DESJARDINS: How do you feel# other people look at Trump supporters?

STEPHANIE DIETZ, Donald Trump Supporter: That# we're fat, uneducated.

Sorry, I have got many degrees,# been to 70 countri LISA DESJARDINS: It is a potent political# force against which Haley has some chance.

THALIA FLORAS, Nikki Haley Supporter:# This is the first time in -- Joe Biden.

LISA DESJARDINS: ... thanks# to voters like Thalia Fl You are a longtime Democrat.

THALIA FLORAS: I am a LISA DESJARDINS: Her office is a# personal museum of primaries past.

THALIA FLORAS: Bernie came to New Hampshire.

LISA DESJARDINS: Walls of photos# sw itching this year to vote for# Haley, initially to block Trump.

THALIA FLORAS: And to be honest with you,# that's part of my thought process.

Having## spent time at all her town halls# and events, I grew to admire her.

LISA DESJARDINS: Meantime, she has lost# some faith with the Democratic Party,## which stripped New Hampshire of its delegates# after the state kept its early primary date,## despite Biden and the party# ordering that it be moved back.

THALIA FLORAS: To say I'm disappointed# is an understatement.

I'm not going to## vote in it because they're not counting my vote.

LISA DESJARDINS: The primary date debacle ended in## the Biden campaign deciding to stay# off the ballot and out of the state.

WOMAN: We need to make sure that we# put Joe Biden on the top of the ticket.

LISA DESJARDINS: So now Biden's fate here is# partially in the hands of grassroots efforts,## one muscular super PAC and a# ragtag campaign of volunteers.

COLIN VAN OSTERN, Joe Biden# Supporter: Super unusual.

No## one involved has d LISA DESJARDINS: Colin Van Ostern is# a former gubernato helped start the effort, first with# six people on a Zoom call.

And no COLIN VAN OSTERN: Hundreds of# people are organizing at this## exact moment all across the state in their# LISA DESJARDINS: As signs lay out, people must# write in Biden's name for him to get their vote.

STEPHANIE ALICEA, Joe Biden# Supporter: This is where we're## at right now.

So let's MILLIE LAFONTAINE, Joe Biden supporter:# I'm very worried that he's going to have## a less-than-delightful showing.

And I think he's -- the Democratic Party# has made it harder for him.

LISA DESJARDINS: Harder for him, but it opens up# a small chance, maybe the only chance, for Biden's## opponents, like author Marianne Williamson,# who's been reaching out to voters here for years.

But none may benefit more than Minnesota# Congressman Dean Phillips, who is a long shot,## but yet also perhaps the best shot any# Democrat has of derailing Biden.

The## once-unknown lawmaker is drawing more people,# including a well-past-capacity weekend crowd.

MAN: Are you guys trying to get in?

LISA DESJARDINS: After a bumpy start, Phillips, a# of PAC money and straddles party lines, stressing# prudence and reform, including of housing.

REP. DEAN PHILLIPS (D-MN), Presidential# Candidate: I'm going to have the best## and br (CHEERING AND APPLAUSE) LISA DESJARDINS: He is blunt about Biden.

REP. DEAN PHILLIPS: I mean, I# don't know how anybo at these numbers and det LISA DESJARDINS: It's working# with some of the young.

ALIYANA KOCH-MANZUR, Dean Phillips# Suppor shot at first too.

I t LISA DESJARDINS: And with some like this# man, who was considering voting for Haley.

MARK MCLAUGHLIN, New Hampshire Voter: If the vote# was right now, I would vote for LI SA DESJARDINS: You don't# think that's a wasted vote?

MARK MCLAUGHLIN: I don't because I -- o I personally don't believe in this# to that where you should probably end up# voting for who you really want to LISA DESJARDINS: All of this is one# question in January about November.

NARRATOR: The two most disliked# politicians in America, Trump and Biden.

LISA DESJARDINS: If the U.S. is to# veer away from a Trump-Biden rematch,## someone else must have a very big# night here, like Phillips or Haley.

BRETT SHEWEY, Nikki Haley# Supporter: I'm afraid that,## Tuesday, if she does not win LI SA DESJARDINS: One more day that could# set the direction for the campaign y One factor here, of course, are independent# or undeclared voters in New Hampshire.

Over## 40 percent of registered voters# are undeclared.

That means they## can vote in either the Republican# or Democratic primary tomorrow.

And, by the way, Geoff, as you know, they# don't like to be told who's going to win.

GEOFF BENNETT: So, Lisa, let's start with the# Republican side.

What does the Haley campaign,## what do they say that she# needs to do tomorrow night?

LISA DESJARDINS: Just a few weeks ago, last year,# Ni even pull out a win here in New Hampshire.# This is a very favorable state for her.

But now, when I talk to them, they're saying they# want to have a strong second place.

Essentially the margin matters a lot.

She has to prove that# she can somehow gain momentum out of this state## especially and try and build something in her# own home state, South Carolina, which is next.

GEOFF BENNETT: And for the Democrats, the# fact that President Biden isn't actively## contesting New Hampshire, that gives a bit# of a window to the longshot of Marianne Williamson and Dean Phillips.# What are you hearing from their campaign?

LISA DESJARDINS: All right, they're keeping# plot twists to our political times.

This is## an extraordinary situation, where President# Biden, as I mentioned, has these challenges of his own making by blocking the New Hampshire# primary from going first, coming off the ballot.

Now voters have to -- who want to actually vote# for him have to look at this.

Let's show you the## New Hampshire ballot.

There you go.

Look at# this long list of names of people who have## qualified for president on his ballot.

At the# bottom, voters would have to write in Joe Biden Now, the secretary of state here in New Hampshire# does have some parameters where it doesn't have## to be exactly Joe Biden.

Essentially, those# reading the ballot have to believe that the## voter intended to write Joe Biden.

Could# be President Biden, those kinds of things.

But there are also challenges not of President# Biden and Democrats' making.

For example,## there was a robo-call that NBC News# got ahold of today in which there was## the voice of Joe Biden manipulated to try# and tell voters that they shouldn't show## up for the poll at all.

It's very# clear that Republicans would love a## situation where Joe Biden underperforms# here, maybe gets less than 50 percent.

I will also say, though, Dean Phillips at# the same time seems to be getting bigger## and bigger crowds.

It was really one of the# few surprises I had here, seeing overflow## crowds for him.

And another strange thing in# these strange times, maybe not so strange,## I have met several voters who are choosing# between Nikki Haley and Dean Phillips.

What do they all have in# common?

The big theme here,## they don't want it to be a Trump-Biden rematch.

GEOFF BENNETT: All right, Lisa Desjardins# in New Hampshire Lisa, thank you.

And be sure to j Hampshire primary.

That's at 11:00# p.m. Eastern right here on PBS.
