Last year’s election was humbling for pollsters, and the Capitol Insiders Survey was no exception. The vast majority of congressional staffers surveyed by CQ Roll Call in the days before the election — 91 percent — predicted a Hillary Clinton win. Only 6 percent thought Donald Trump could pull it off.

Still, the results reflect how Trump’s win blindsided the Washington establishment. The majority of Republican aides said consistently during the campaign that they wouldn’t vote for Trump.

Those tensions have carried over into 2017, in what has proved to be perhaps the least productive first 100 days for any president in modern history.

The most recent poll results, from April, show why: Republicans on Capitol Hill are still not comfortable with Trump, who, even during his so-called honeymoon, has not yet convinced his party to back a repeal of President Barack Obama’s health care law, even as he touted House passage of a bill that would do it.

But Republicans don’t have a monopoly on infighting. Democratic respondents are torn between those who’d like to stonewall Trump at every turn and those who think it wiser to look for areas of compromise.
