A new Morning Consult poll finds Trump leading the Republican field with 22 percent of the vote, well ahead of former Florida Gov. Jeb Bush, who clocks in with 15 percent, and Wisconsin Gov. Scott Walker, in third place with 12 percent…

There is no evidence that Trump’s numbers have slumped after comments he made questioning Sen. John McCain’s (R-Ariz.) war record. Though most of the rest of the Republican field — and even the Republican National Committee — loudly criticized Trump after he made the comments on Saturday morning at an event in Iowa, voters interviewed afterward weren’t any less likely to say they support him.

In fact, Trump has gained ground since a Morning Consult poll earlier this month, when he trailed Bush by a 19 percent to 17 percent margin. This week Trump is the second choice of 12 percent of voters, behind Bush’s 18 percent.

But both this week’s and last week’s polls suggest Trump’s ceiling is lower than other candidates. Republican voters have a broadly favorable impression of candidates running for their party’s nomination; 63 percent of self-described Republicans have a favorable view of Bush, while 27 percent see him unfavorably, for example.
