Tyler Olson at Fox News:
"President Trump didn't have a serious challenger in the New Hampshire primary, but he still turned out enough voters to more than double former President Barack Obama's 2012 vote total in the state, indicating that the Republican base is all-in on Trump as he prepares to face the eventual Democratic nominee in a reelection battle this November.
...It follows a coordinated effort by the Republican National Committee and the Trump campaign to drive up turnout for Trump in New Hampshire -- something the other incumbents didn't do. Trump himself revved up his supporters at a packed and fiery rally in Manchester, N.H., on Monday, the eve of the state's primary."
"Nine months from now, we are going to retake the House of Representatives, we are going to hold the Senate, and we are going to keep the White House," Trump said to thunderous applause. "We have so much more enthusiasm, it's not even close. They're all fighting each other.
...The throngs that showed up for Trump's Monday rally at Southern New Hampshire University were more than the school's venue could hold with its 11,000 capacity, and the president took the opportunity to tout his accomplishments and knock Democrats in front of the large audience."
Primary history in New Hampshire is on Trump's side.
