Analysis: The best unused unity argument
All the Democratic candidates are making the case that they can bring their party and the country together. Some focus more on the former and some more on the latter, but both will be needed for one of them to win the presidency.
Minnesota Sen. Amy Klobuchar likes to point out that she won a lot of counties in her 2018 Senate re-election bid that President Donald Trump also won in her state in 2016. It's not the best comparison because Klobuchar was running against a pretty underwhelming opponent. Her first Senate victory — and the oft-cited fact that she's never lost an election — is probably a better testament to her ability to win a race against a Republican.
But what she hasn't really trotted out is perhaps the most compelling storyline any of the Democrats could tell about unifying the party. While she has critics within her party at home, Klobuchar hasn't been targeted for primary defeat by the left the way that many other senators have. She's been strong across her party in Minnesota — and that's no small feat because it's the Democratic-Farmer-Labor Party.
None of the other presidential candidates comes from a state with a Democratic congressional delegation as ideologically diverse as Klobuchar's, which features conservative Rep. Collin Petersen, who voted against impeaching Trump, and Rep. Ilhan Omar, who is among the most liberal members of Congress. In her Senate races, Klobuchar has to win backing from farmers along the state's border with the Dakotas, union members in the Lake Superior region, and a diverse mix of voters in the Twin Cities and their suburbs. Minnesota's DFL is a uniquely big-tent version of the Democratic Party, and Klobuchar may start to talk more about it.
'The Conners' sitcom to air live with real-time New Hampshire results
News organizations around the U.S. will be concentrated on New Hampshire tonight — and so will one sitcom.
ABC's "The Conners" will be doing a live episode at 8 p.m. ET that uses the results from the New Hampshire primary as part of the episode.
Few TV shows have tried such a stunt, but a 1997 episode of "ER" comes to mind, which was live and incorporated a playoff game between the Chicago Cubs and the Houston Astros.

Most voters think Trump will win re-election, new poll finds
Two-thirds of voters believe that President Trump will be re-elected in November, according to a Monmouth University poll released Tuesday. Of those, 27 percent said they think Trump will "definitely" be re-elected, while 39 percent said they feel he will "probably" win again.
The poll also finds that just 11 percent of registered Democrats say their party's eventual nominee will "definitely" beat Trump, while 38 percent said "it is more likely than not" that Trump will win.
In the Democratic primary race, the poll shows a new front-runner, with Vermont Sen. Bernie Sanders leading the field at 26 percent support among Democratic and lean-Democratic voters — up from 23 percent in the last national Monmouth University poll, taken before the Iowa caucuses. Former Vice President Joe Biden fell to 16 percent support in this poll — in January he was at 30 percent.
How New Hampshire votes: Pencils and paper
New Hampshire’s election system is decidedly old school: paper ballots hand-marked by voters.
That’s mostly a good thing, election technology experts told NBC News. After Iowa’s caucuses were thrown off in part due to a faulty smartphone app, election technology is now the focus of national scrutiny.
But like any election system, New Hampshire’s isn’t bulletproof. Aging equipment and a few tweaks to its system for 2020 still present opportunities for confusion or disruption for Tuesday’s vote.

5 Things to watch in New Hampshire: Why losers matter as much as winners
Tuesday's first-in-the-nation New Hampshire primary, which is marking its 100th anniversary, may be more important than it has been in years in deciding the future of the Democratic presidential field, with a number of once-leading candidates teetering on the brink of oblivion and some former no-names gaining steam.
The state is famously unpredictable and can swing faster than polls can capture, especially because independent voters, who outnumber Democrats and Republicans, can vote in the primary.

Biden says he's New Hampshire 'underdog," but still the best candidate to beat Trump
Former Vice President Joe Biden told MSNBC's "Morning Joe" on Tuesday that he sees himself as the "underdog" in the New Hampshire primary after finishing fourth in the Iowa caucuses and with his rival Sen. Bernie Sanders, I-Vt., leading polls in the Granite State.
"I think I’m an underdog here, and Bernie won this by 20 points last time," Biden said. "He’s got a next-door neighbor advantage and he’s got a real enthusiasm going here, but I still feel good. This is, you know, it’s a long haul."
Biden said he thinks he is still the best candidate to beat Trump because he can win over working-class voters.
"I think Donald Trump’s demonstrated the last guy he wants to run against is me," he said. " And look, I have always done extremely well in places like Pennsylvania, and I’ve done extremely well in the South as well."
Biden also challenged former New York City mayor and billionaire businessman Mike Bloomberg's support among black voters — a core constituency of the Democratic party and a large part of Biden's lead in national polling.
"I’m looking forward to debating Mike Bloomberg about his support for African Americans," Biden said.
The former vice president repeated his criticism of Sen. Bernie Sanders' embrace of democratic socialism, saying that running on socialism would be a problem in the general; however, Biden would not say he thinks Sanders is unelectable.
"I refuse to suggest any Democrat can lose," he said. "I think, you know, we could run Mickey Mouse against this president and have a shot."
