What are the top issues expected to be discussed at the debate?

Wednesday’s GOP presidential debate is being moderated by Fox News anchors Bret Baier and Martha MacCallum. 

Fox News Anchor Martha MacCallum, who will moderate Wednesday’s debate in Milwaukee, Wisconsin with fellow Fox News anchor Brett Baier,  shed some light on her expected approach to the debate questions. 

"One of the things that you really want to accomplish here is to give people a chance to share with the audience what they would do to make the country better," MacCallum said. “And then you have to get at it from a political angle as well, because there's a lot of strategy that's involved in how one of these people is going to jockey themselves into being the contender, or one of maybe a couple of contenders who make it through the early stages of this process, starting with the debate, in order to get into that head-to-head position with the former president, Donald Trump."

MacCallum added, "We really want people to walk away from the debate on Wednesday night feeling like they can have a better sense of all these people and maybe their eyes are open to one or two of them that they want to hear more from. I think that's honestly, that's the main goal, is to move this process forward in a way that people feel is edifying and that they are more interested in the morning after on Thursday."

Nine candidates reached the polling and donor thresholds required by the Republican National Committee to qualify for the Milwaukee debate: Former President Donald Trump, former Vice President Mike Pence, Florida Gov. Ron DeSantis, Sen. Tim Scott of South Carolina, former Ambassador and former South Carolina Gov. Nikki Haley, former New Jersey Gov. Chris Christie, North Dakota Gov. Doug Burgum, biotech entrepreneur Vivek Ramaswamy and former Arkansas Gov. Asa Hutchinson.

Trump said on his social media app Truth Social Sunday he will "not be doing the debates."
