Donald Trump is leading the pack among candidates for the 2016 Republican Party nomination in the latest batch of polls.

A CNN Poll on Sunday showed Trump leading with 18% support among Republicans. Former Florida governor Jeb Bush was second at 15%; Wisconsin Governor Scott Walker rounded out the top three at 10%. Trump’s ratings in the poll have surged 6 points in the last month, while his rivals have remained relatively steady.

And while the poll is by no means a reflection of who will take the Republican Party nomination in 2016, it suggests Republicans are excited by a Trump candidacy. Fifty-two percent of Republicans want to see Trump continue his run and 42% of Republicans currently backing another candidate want Trump to remain in the field.

CNN’s survey is in line with an NBC poll of New Hampshire voters, also released Sunday, showed Trump holding 21% of Republican support, with Bush trailing at 14% and Walker at 12%.

In an NBC poll of Iowa Republican voters, Walker is leading the pack at 19%, with trump narrowly behind at 17%. Bush follows them at 12%, then Ben Carson at 8%, Mike Huckabee at 7%, and Rand Paul at 5%.

And yet another poll from YouGov goes further, showing Republican support for Trump at 28%.

Trump’s surge came after a week of strong, united Republican rebuke on the candidate’s controversial comments on Sen. John McCain’s service and suggesting the Vietnam War veteran was “not a war hero.”

“A number of my competitors for the Republican nomination have no business running for president,” Trump wrote in USA Today. “I do not need to be lectured by any of them.”
