The New Hampshire primary winners are Donald Trump on the Republican side and Bernie Sanders in the Democratic race. Each took the top spot after second-place finishes in the Iowa caucuses.
Trump's first victory of the 2016 White House race means he's no longer a political rookie but the front-runner for his party's presidential nomination.
And the win for Sanders completes his rise from presidential long shot to legitimate challenger for the Democratic nomination against Hillary Clinton.
With 24 at stake, Sanders stands to gain at least 13. Hillary Clinton will receive at least seven.
Clinton remains ahead in the overall delegate count due to support from superdelegates -- the party officials who can support the candidate of their choice.
Including superdelegates nationwide, Clinton has amassed at least 392 delegates and Sanders at least 42.
With Tuesday's win, Trump will take the lead in the race for delegates for the Republican National Convention.
It won't be much of a lead.
There are only 23 delegates at stake in New Hampshire's Republican primary, and they are awarded proportionally, based on the statewide vote.
Trump will win at least nine. The final tally depends on how many candidates get more than 10 percent of the vote, the threshold needed to qualify for delegates.
