Alexander Bolton, The Hill:
Donald Trump has coasted to big victories in the New Hampshire and South Carolina primaries, strengthening his position as the pole-setter in the Republican presidential race.
It’s a nightmare scenario for GOP senators clinging to their majority.
“I think they’re very concerned if they’re up for reelection,” said former New Hampshire Sen. Judd Gregg (R).
“I imagine [Senate Majority Leader Mitch McConnell (R-Ky.)] is more than concerned because clearly Trump at this time is not going to carry swing states,” Gregg added.
“I’m thinking of New Hampshire, for example.”
New Hampshire Sen. Kelly Ayotte is one of five endangered Senate Republican incumbents running for reelection in states won in 2008 and 2012 by President Obama.
