In Iowa, Republicans indifferent to Democratic caucuses. No one can beat Trump, they say

Bernie, Mayor Pete, Biden it doesn'tmatter whowins the Iowa Democratic caucuses because not one of them stands a chance against Donald Trump.

At least that was the general attitude among manyTrumpsupporters who filled the rafters of Drake University in Des Moines Thursday night, just days before theIowa caucusesofficially kick off the presidential nomination process.

"None of them," saidTed Reeve, a home builder from Des Moines, when asked which Democratic candidate would give Trump the most trouble in the general election. "Trump will win in a landslide. I don't think it will even be close."

"None of them,"was by far the most popular answer given by Trump supporterswhen asked who posed the greatest challenge to Trump.

But even if his supporters here don't believe these Democrats pose a threat,Trump's appearance in Iowa is no accident.

While he won the state handily in 2016, it could be competitive this year, saidIowa State University political science professor David Peterson.

The state'seconomyhas been slowing down, even as growth is strong in the rest of the country, said Peterson.The trade war has been particularly hard on Iowa farmers, who are quite good at seeing the direct link between federal policy and their bottom line, he said.

That means Trump's appearance, days before thecaucus, is to remind Iowa Republicans and Trump-leaning independents why they like him, Peterson said.

The crowd atDrake University's Knapp Center certainly needed no reminding. The thousands who had crammed insidea near sea of red MAGA-like ball caps dotting the arenaloudly showed theirsupport when the U.S. president took the stage. Some had waited in the cold for hours to get in, with a few, according to the Des Moines Register, camping outside the day before.

Hundreds of others who couldn't get inside stood outdoors, watching Trump's speech on a big screen. Not all were fans. Dozens of protesters also stood nearby to condemn the president.

Impeachment riles base

While Trump's presidential fate was being debated in Washington, D.C., through an impeachment trial, here in Iowa, the topic has angeredhis base, seemingly ensuring they will come out and vote.

It's totally political," said John Golnick. "The Democrats have hated Trump even before he was elected."

Many supporters of Trump, who has beenaccused of withholding aid to Ukraine in order to persuade government officials to investigate potentialpolitical rival Joe Biden and his son Hunter, believe he didn't do anything wrong and certainly nothing that would necessitate impeachment.

"They'regetting peopleriled up, as they say in southern Iowa," saidRoger Burdett."They're helping him get elected."

In fact, Trump's competitionis so weak that Burdett predictedthe president will win an even larger mandate in the 2020 presidential election.

Take Bernie Sanders, for example,and what seems to be his growing momentum in the Democratic nomination race. Many at the rally agreed Sanders and Trump share at least one thing in common areal passion and enthusiasmamong their core supporters.

Still, "he doesn'thave a chance in hell of winning," Burdettsaid of Sanders.

Steve Ward, a rancher from Wyoming who drove in to see Trump, also dismissed the Vermont senator as a viable challenger. "Good luck Bernie," Ward said, smiling. "Bernie just don't have it."

Reeve's wife, Patty, who is an accountant, summed up what many of Trump supporters thought of Sanders's chance of victory in a general election:"I think his socialist views are just way too far left."

Others also dismissed Biden, saying Americans would look unfavourably at his record as vice-president and give him a big pass, although Iowan Brian Belew said a Trump-Biden matchup "wouldbe fun to watch."

But there wasone Democratic candidate, mentioned a few times, who seemed to give them slight pause:PeteButtigieg.

Kelly Bennett, a financial planner from Antkenny, Iowa, believed the former mayor of South Bend, Ind., would have the best chance to compete against Trump.

"I think that he has common sense appeal. I think he's a little more moderate," Bennett said. "I think he can dip into the Trump vote, the moderate, common sense swing vote that went Trump's way last time.

"I think he could get some of that to swing back the other way."

Trump madementionof the Democratic candidates during his Iowa rally Thursday, mocking their namesand referring to them as "theradical Democrat socialists who are right down the street."

He also wondered out loud, half-jokingly, if Hillary Clinton took another run at the presidency, who would give him the hardest time: her, Sanders, Buttigieg or Biden?

Trump supporter Belew had an answer for that."I cannot think of anyone."
