In the Senate, where the majority is even more tenuous, lawmakers are practically running from the question. Asked about Trump, Sen. Roger Wicker (R-Miss.), chairman of the National Republican Senatorial Committee, said he makes a practice of avoiding commenting on presidential politics. New Hampshire Sen. Kelly Ayotte, up against Democratic Gov. Maggie Hassan in what’s expected to be a very competitive race, refused to discuss Trump.

“I focus on what I do every day in my job,” Ayotte said. “He can focus on his presidential campaign.”

Still, she quickly moved to distance herself from Trump’s policy position on Muslim immigration. Ayotte has also cosponsored a bill that would require foreigners, who would normally be able to travel to the United States without a visa, to apply for one if they had recently traveled to Iraq or Syria.

“I don’t think there should be a religious-based test for our immigration standards,” Ayotte said. “It should be a fact-based risk assessment on our immigration system, which is what we have. … [W]e need to enhance that system to make sure we address the risks of those who have, of course, connected or tried to connect with ISIS, and/or have traveled to Iraq and Syria.”
