Publishing magnate Steve Forbes weighed in on the Republican presidential race Saturday and said that Trump would do well with unions, even if union leaders pull for a Democratic candidate.

“[Union leaders] may endorse a Democrat like Hillary ClintonHillary Diane Rodham ClintonGrassley blasts Democrats over unwillingness to probe Clinton GOP lawmakers cite new allegations of political bias in FBI Top intel Dem: Trump Jr. refused to answer questions about Trump Tower discussions with father MORE, but the rank and file, a big chunk of them are going to go their own way," Forbes said on a radio interview with John Catsimatidis. 

He also said a big part of Trump's appeal is his attitude in speeches. 

"Trump, even as he criticizes and throws out charges and all that kind of thing, he always ends up on an upbeat note about the USA," Forbes said.

"People want that, people want to hear that. They're tired of all this gloom and doom, and 'the U.S. is going in a trash heap.'"

When asked for his opinion on the rest of the GOP field, the Forbes Magazine founder added that Marco RubioMarco Antonio RubioRyan pledges 'entitlement reform' in 2018 Richard Gere welcomes lawmakers' words of support for Tibet Dem lawmaker gives McConnell's tax reform op-ed a failing grade MORE and Ted CruzRafael (Ted) Edward CruzDebbie Wasserman Schultz marks 10 years as breast cancer survivor Foreign agent registration is no magical shield against Russian propaganda Let Trump be Trump and he'll sail through 2020 MORE should seek to imitate Trump's rhetoric.

"Well Ted Cruz has got to get a, I think, more upbeat note. He's got some good ideas on gold, he's got some good ideas on taxes, but he's got to be a little more Reagan-esque in his speeches," he said.

"Rubio is trying to do that, he's getting better at it. I just wish he'd make his tax plan better, he's got the worst tax plan out there," Forbes added. "Better than what we have now, but not up to par with the other Republican candidates."
