Republican presidential candidate Donald Trump today said he’s put Hillary Clinton on notice as to what’s “fair dialogue” in the political campaign.

Last week Clinton told The Des Moines Register Trump has a “penchant for sexism” that was illustrated when Trump used a vulgar term to describe Clinton’s loss to Obama in 2008. During an interview with Radio Iowa today, Trump said he won’t let Clinton use the “woman’s card” against him.

“With all of her past and her past dealings and, frankly, she’s been involved in it with her husband as much as anybody, for her to be discussing that I think is out of bounds and I’ve let them know that. I think we have to have fair fights here and fair dialogue and we have to do what’s right for the country and she shouldn’t be discussing it. Probably maybe more so than anybody I know she shouldn’t be discussing that,” Trump said, with a laugh. “So I let them know that…and I think it’ll end up being a fair fight.”

Trump did not directly mention Bill Clinton as he talked with Radio Iowa, but in other media Trump has referred to Bill Clinton’s “very troubled” presidency and Trump tweeted that Bill Clinton has a “terrible record of woman abuse.”

During his Radio Iowa interview, Trump discussed his prediction that the country is headed toward recession, his objection to a “loyalty oath” for Republican voters in Virginia and his Iowa campaign effort. Trump said his supporters are troubled by how far the country has fallen.

“We can’t even beat a 40,000 group of people called ISIS,” Trump said. “…Everything is bad — our health care, our military, our borders.”

Trump recently said he’s switching to a new campaign phase, trying to unify the GOP, but that risks alienating potential Trump voters who like his combative, anti-establishment style.

“I think to a certain extent I already have blown up the party. You know, the party is very disjointed right now and you’ve got to win an election and the best way to win the election is if everybody, ultimately, can get together,” Trump said. “If I get the nomination, I’d rather have people on my side than against, but I’ll do whatever I have to do to do it right.”

Earlier this month Trump told a crowd in Cedar Rapids that he has “an incredible ground game” in Iowa to spur turn-out on Caucus night, including people “who have never voted before.”

“I think we’re doing really well in Iowa…even better than the polls would suggest and the polls have us at least in first place,” Trump said today during his Radio Iowa interview. “So I think we’re doing really well.”

Trump went on Twitter Sunday to blast the Virginia Republican Party for requiring voters in that state’s GOP Primary to sign a statement to confirm they are a Republican. Trump argues it will discourage new voters and Democrats who might cross-over and vote in that state’s Republican Primary on March 1.

“You never really know for sure, but I would say it would hurt me because I get tremendous numbers of outside people,” Trump said.

Trump said the next president must “act quickly” to revive the U.S. economy.

“If you don’t get the right president, it’s going to be a mess because we’re sitting on a bubble — a big, fat, very ugly bubble,” Trump said. “…It could happen during the Obama Administration and frankly if it does happen I’d much prefer that because I’d rather go in and fix it than have it linger because it’s lingering and it’s a very, very serious problem for the country and I know how to get it fixed.”

Trump is also blasting Republicans in congress for capitulating and giving Obama “everything” he wanted in the massive spending bill that cleared congress earlier this month.

“That horror show that was passed, the budget, the way they did that,” Trump said. “….It’s almost not even believable that they were allowed to pass a budget like that and that the Republicans, which have now a majority, that they’re allowing things like that to go on. I thought when we took the Senate and you have the House that all of a sudden it would change and I think it’s worse than ever before.”

Trump is due in Council Bluffs tomorrow for a rally at the Mid-America Center. The doors open at 5 p.m. and it’s scheduled to start at 6:30.
