Donald Trump leads GOP field: Why aren't conservatives excited?

Nearly 32 percent of Republicans surveyed said they backed Donald Trump, up from 24 percent a week earlier.

Republican Donald Trump is pulling away from the pack in the race for the party's U.S. presidential nomination, widening his lead over his closest rivals in the past week, a Reuters/Ipsos poll showed on Friday. But Trump has yet to win over conservative activists, based on interviews at a gathering in Ohio.

Most Republican voters show no signs they are growing weary of the brash real estate mogul, who has dominated political headlines and the 17-strong Republican presidential field with his tough talk about immigration and insults directed at his political rivals. The candidates are vying to be nominated to represent their party in the November 2016 general election.

Nearly 32 percent of Republicans surveyed online said they backed Trump, up from 24 percent a week earlier, the opinion poll found. Trump had nearly double the support of his closest competitor, former Florida Governor Jeb Bush, who got 16 percent. Retired neurosurgeon Ben Carson was third at 8 percent.

Even when Trump was pitted directly in the poll against just his top two competitors, 44 percent backed him. Bush won about 29 percent of respondents, and Carson 25 percent.

"He's not taking any guff from anybody," Dewey Stedman, 70, a Republican from East Wenatchee, Washington, said of the publicity-loving billionaire. "If you don't have something in your brains, you're not going to have billions of dollars."

Trump has driven the debate on the campaign trail with a hard-line immigration plan that calls for the deportation of undocumented immigrants, amendment of the Constitution to end automatic citizenship for all people born in the United States, and construction of a wall along the border with Mexico.

He also has feuded with Bush and other rivals while boasting he could easily beat Democratic front-runner Hillary Clinton.

Trump's campaign momentum has paid off with bigger crowds on the campaign trail. On Friday night, he moved a planned rally in Mobile, Alabama, to a football stadium seating more than 40,000.

"It is an appeal to people that are just aggravated about what's going on," Republican strategist Rich Galen said, adding that Trump is a "novelty act" that voters will tire of.

Friday's results in the online rolling opinion poll are based on a survey of 501 Republicans and have a credibility interval of plus or minus 5 percent.

Separate results found Clinton leading among Democrats, though support for her dipped below 50 percent to 48.5 percent.

U.S. Senator Bernie Sanders of Vermont came in second in the poll of 625 Democrats, followed by Vice President Joe Biden, who has not entered the race. That survey had a credibility interval of plus or minus 4.5 percent.

Why conservatives are luke warm

While thousands streamed into a football stadium Friday evening in Mobile, Ala., to see Trump, a much smaller crowd of committed conservatives unwound at a bar and mused over the good, the bad and the unknown of the unlikely Republican presidential front-runner.

They were volunteers and staff for Americans for Prosperity, a non-profit group funded by industrialist billionaire brothers Charles and David Koch, two of the most effective conservative activists in U.S. politics.

According to AFP, 3,600 people came to this year's annual Defending the American Dream Summit from around the country Friday and Saturday, taking in appearances by a handful of the 17 Republican presidential candidates. Trump was not invited.

On the national level, Trump is dominating the contest for the 2016 Republican presidential nomination and widened his lead over the crowded field. But among this self-selected group of politically engaged conservatives, his popularity has yet to solidify. Trump the phenom dazzles, but Trump the candidate is getting the same scrutiny as the other 16 Republicans.

The apparent reticence among this influential grouping plays into one of the big political questions of the moment: Can Trump turn his strength in the polls and undeniable attractiveness to a slice of voters into victories in Republican primary elections early next year?

In the mid-term 2014 elections, AFP achieved a 95 percent success rate in the election races where it spent money. As a non-profit, it cannot advocate for specific candidates, but it runs ads to defeat candidates who it believes are not doing a good job on specific issues.

AFP President Tim Phillips told Reuters on Saturday the group would keep its "laser" focus on advocating for issues like tax reform, repealing the Affordable Care Act and fighting environmental regulations, no matter who is elected.

Former Florida Governor Jeb Bush, Texas Senator Ted Cruz, Louisiana governor Bobby Jindal, former Texas Governor Rick Perry, and Florida Senator Marco Rubio were among the scheduled speakers. When it came to choosing candidates to invite to the summit, Phillips said "We talked to people who had records that for the most part were philosophically aligned with us."

"We didn't want a cattle call," he added, while noting that Trump had appeared at past AFP events.

AFP officials don't mince words about politicians they dislike and Phillips recalled how AFP was critical of Cruz during the government shutdown two years ago.

Summit attendees did advocate for candidates, wearing preferences on t-shirts, buttons and hats, supporting the likes of Cruz and another candidate, retired neurosurgeon Ben Carson.

Though it wasn't hard to find people who said they liked Trump, the fervor that has driven the brash New York businessman to the top of the polls was a more reserved admiration here, an approval of the voice in the abstract rather than the candidate.

"It really frustrates me when he bashes other candidates - and they're really cheap personal shots," said Althea Cole, 31, a Republican from Cedar Rapids, Iowa who is a county chairwoman there for Carson's campaign. Still, she had some admiration for Trump's success.

"The man's a jackass, but you don't get to be a billionaire by making friends," she said.

A group of college students in a Republican club at Augustana College in South Dakota felt he was too much of a bully.

"He's mocking it with his presence," said Cara Beck, 20, as she stood with five male students between 19 and 21 years of age. Their picks were Bush, former Ohio Governor John Kasich, Kentucky Senator Rand Paul and Rubio.

Among a group of young Tennesseans, Trump garnered mixed reactions - plaudits for his business acumen, and boos for the reality TV star's showmanship.

"Both my parents love Donald Trump but I can't stand him," said Michael Stooksbury, 18, who likes Paul best. "He doesn't have any experience, he's just an entertainer."

But Thomas Parham, 29, said the country could benefit from Trump's business background.

"I'd rather us be a financial empire than an empire of war," he said, "that way we can take over country after country, territory after territory, without firing a single shot."
