MANCHESTER, N.H. (AP) -- 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.

In a victory speech after the polls closed, Sanders said his New Hampshire win sends a "message that will echo from Wall Street to Washington."

New Hampshire's secretary of state says voter turnout in Tuesday's presidential primary is likely to be slightly higher than in 2008.

After her loss in New Hampshire, Clinton said she would "take this campaign to the entire country."

Bill Gardner predicted several days ago that roughly 282,000 Republican ballots cast would be and 268,000 Democratic ballots cast.

He says his visits to various polling places Tuesday lead him to believe his predictions are on par.

Even if Republican Trump or Democrat Sanders were to stumble, the two were assured of moving on. However, for some GOP candidates, the outcome could determine whether their campaigns continue beyond the northeastern battleground.

Ohio Gov. John Kasich finished second in the state's Republican presidential primary.

A trio of governors — Jeb Bush, Chris Christie and Kasich — have spent most of their time in the state in recent weeks and needed to show voters, as well as crucial financial donors, that they're viable candidates.
