One week after the US election race began in chaotic fashion, the contest moves on to New Hampshire on Tuesday.
Voters in the north-eastern state are choosing their preferred nominees for the 2020 presidential election race in a primary contest.
Bernie Sanders, a liberal firebrand, appears best placed to perform well in New Hampshire.
Results from the first Democratic contest last week, in Iowa, were held up by technical glitches.
The aim of the primaries and caucuses is to win as many delegates as possible across all states and territories, in order to be confirmed as the candidate.
Joe Biden might have expected to arrive in New Hampshire in more buoyant form.
He was among the frontrunners in the opening Iowa caucuses last Monday but in the end, he lagged well behind. The former vice-president claimed fewer delegates than rivals Mr Sanders, Pete Buttigieg and Elizabeth Warren.
Realistically, it’s a competition for third place between Mr Biden and Ms Warren in New Hampshire. A poor performance there could put them both on the back foot only two states into primary season, and it’s unusual (though not unprecedented) for someone to win the candidacy
from such a position.
But it’s not all bad news for Mr Biden – he is more popular in states that are more diverse than Iowa and New Hampshire, and the next two contests are in states with large Latino and African-American populations, Nevada and South Carolina.
One piece of context
New Hampshire’s contest is not like Iowa’s – these are primaries, not caucuses like in Iowa. The difference? Caucuses are a convoluted process, where people gather for a few hours for a party meeting and vote publicly in stages. They require quite a bit of commitment.
Primary voters, on the other hand, can just turn up at a polling booth and vote in secret. Then leave. As a result, participation will be much higher.
And because primary voters make their choice using pencil and paper, there should be none of the technical headaches we saw in Iowa.
Is Bernie Sanders electable? We asked two voters in New Hampshire – the daughter is a big Bernie fan, the father a lapsed supporter.
As you’re reading this, some voters have already cast their ballot.
Quirks of the New Hampshire electoral system mean that places with a certain number of residents can vote when they like – including the middle of the night.
So the residents of three hamlets – including Dixville Notch, near the Canadian border – started casting their ballots after midnight, as is traditional.
“We take this seriously,” Tom Tillotson, a Dixville Notch resident overseeing the vote, told Agence France-Presse, adding: “We were humbled and honoured to be… basically the starting gun for the primary election process.”
Until recently, Dixville Notch had only four residents, which would not have been enough for it to vote early. Then one resident decided to move back, and everything was OK again.
The tiny hamlet voted on Tuesday for billionaire former New York Mayor Michael Bloomberg as their preferred candidate.
