The eight leading Republican candidates took the stage for the fourth presidential debate hosted by Fox Business Network yesterday at the Milwaukee theater in Milwaukee, Wisconsin.

The participants in the debate include Donald Trump, Ben Carson, Marco Rubio, Ted Cruz, Jeb Bush, Carly Fiorina, John Kasich and Rand Paul, in the order of poll rankings.

The debate last night centered on the economy, with topics encompassing tax plans, minimum wage, banks, international trade, and foreign policy issues.

The moderators for the debate were Maria Bartiromo, Fox Business Global Markets editor, Neil Cavuto, Fox vice president of business news and Gerard Baker, Wall Street Journal editor-in-chief. In the last GOP debate, the moderators were criticized for their confrontational tones, but Bartiromo, Cavuto, and Baker successfully kept their questions neutral.

“When it comes to substantive issues do we ever hear [Trump] speak? No. If you notice, he lays back when the stuff gets detailed,” Charles Gasparino, Fox Business Network senior correspondent, said after the main event. “If I was looking at a candidate that was both presidential and substantive, it had to be Rubio. He came across like he knew what he was talking about, and he was confident.”

A sample moment from the debate included Donald Trump claiming that he would work well with Vladimir Putin, the president of Russia, because they spent time together in a green room for “60 Minutes,” an hour long TV series by CBS about popular topics in America. However, the two were in different countries during the episode.

Fiorina, the only female candidate onstage and a subject of his previous comments, disagreed with Trump’s position and advocated against speaking to Putin.

“One of the reasons that I have said that I would not be talking to Vladimir Putin right now, although I have met him as well, not in a green room for a show, but in a private meeting, is because we are speaking to him from a position of weakness brought on by this administration,” Fiorina said.

Before the main event, a smaller debate took place among candidates with one to two and a half percent in the poll. In the order of the poll rankings, the participants in the undercard debate were Mike Huckabee, Chris Christie, Bobby Jindal and Rick Santorum.

“I think both Bobby Jindal and Chris Christie had their moments, but it seemed to me that Chris Christie was a cut above the other candidates on the stage tonight,” Steve Hayes, a senior writer at The Weekly Standard, said during post-debate commentary on Fox. “He came in this debate wanting to take the argument to Hillary Clinton. It played well with the audience in the theater, and I’m certain it played well with viewers back home.”

A common theme agreed upon by the Republicans across the debate was the assertion that Hillary Clinton will ruin the country if she is elected. Clinton’s name was mentioned twenty-five times over the course of the evening by the candidates. All eight debaters in the main event criticized Hillary Clinton at least once during their time.

The next Republican debate is scheduled for Tuesday, Dec. 15 in Las Vegas. It will be hosted by CNN and Salem Radio and moderated by Wolf Blitzer, CNN’s lead political anchor.
