Following Donald Trump's speech expressing "regret" for comments he has made throughout the course of his campaign, supporter and former House Speaker Newt Gingrich predicted the Republican nominee would prevail in November against Hillary Clinton.

"I'm going to go out on a limb tonight and you can keep this tape and remind me about it after the election, OK? Donald Trump’s going to win," Gingrich told Fox News' Sean Hannity on Thursday night. "Donald Trump’s going to win because in the end the country is not going to reward big banks and big unions and big bureaucracies and big donors and big corruption by voting for a big liar. And in the end, the country is going to say, you know, whatever Trump's weaknesses may be, he's a sincere guy trying very hard to get this country back on the right track."

Gingrich had previously expressed frustration with Trump's performance following the Republican National Convention, warning that the GOP nominee needed to stick to the issues and not go after anyone not named Clinton. And he also admonished establishment Republicans who are still opposed to supporting Trump.

"Now if a bunch of Republicans are too stiff-necked, too proud or in some cases too committed to the old order, after the election I think they're going to be very sobered by this, their position," Gingrich said. "Because the fact is I think he's going to win."

Hannity, a staunch Trump supporter, responded, “I hope and pray you're right because I don't think we can survive four more years of these failed policies.”
