New Hampshire Takeaways: Donald Trump proves he's a winner

The longtime Republican front-runner proved he can do more than just top preference polls by posting a dominant victory in the nation's first primary state.

The brash billionaire was already far ahead of the fractured GOP field in polls of next-to-vote South Carolina before Tuesday's win, and it should be expected that he'll get a boost of momentum coming out of New Hampshire.

Hounded by Chris Christie in the final debate before Tuesday's primary for what the New Jersey governor argued is his thin record of accomplishment, Rubio repeated a line from his standard stump speech four times.

Sanders won an overwhelming majority of young voters, a significant part of the coalition that twice helped elect Barack Obama.

[...] Sanders and Clinton were evenly divided among women, a major setback for a candidate who aims to become the nation's first female president.

Clinton campaign manager Robby Mook wrote in a memo that her campaign is well-positioned among black and Latino voters who are prominent in Nevada, South Carolina and the March contests.

[...] the resounding loss in New Hampshire, which Clinton won in 2008 and where her husband revived his flagging campaign in 1992, creates the potential for the party's diverse electorate to give Sanders a second look.

Among Democrats, voters said they valued honesty over other qualities in a candidate — including experience, caring about people like them and electability.

Among those saying they want a candidate who "tells it like it is" over other qualities, two-thirds voted for the real estate mogul and former reality TV star.

Money is about to get tight for several candidates who just unloaded much of their campaign coffers in New Hampshire, a state where it costs a lot to broadcast TV ads.
