The Fox Business Network, which is hosting next week’s GOP presidential primary debate in Milwaukee, Wisconsin, rolled out which candidates made the main stage and which ones made the undercard stage.

The debate, which will happen on Tuesday evening, will feature Ohio Gov. John Kasich, former Florida Gov. Jeb Bush, Sen. Marco Rubio (R-FL), billionaire Donald Trump, Dr. Ben Carson, Sen. Ted Cruz (R-TX), former Hewlett Packard CEO Carly Fiorina, and Sen. Rand Paul (R-KY) on the main stage.

On the undercard stage, the following candidates will appear: New Jersey Gov. Chris Christie, Louisiana Gov. Bobby Jindal, former Pennsylvania Sen. Rick Santorum, and former Arkansas Gov. Mike Huckabee.

Fox Business’ Managing Editor of Business News Neil Cavuto, Global Markets Editor Maria Bartiromo, and Wall Street Journal Editor in Chief Gerard Baker will moderate the main stage debate.

FBN’s Sandra Smith, Trish Regan, and WSJ’s Washington Bureau Chief Gerald Seib will moderate the undercard debate.

This means that the following candidates did not qualify for any debate: Former New York Gov. George Pataki and Sen. Lindsey Graham (R-SC). Former Virginia Gov. Jim Gilmore failed yet again to even qualify for the undercard debate, as he’s done the first three times.

Huckabee and Christie lost their slots on the main stage. Both have been on the main stage for the first three debates.

This is the fourth debate. The undercard debate will air from 6 p.m. to 7:30 p.m. ET. The main stage debate will air from 9 p.m. to 11 p.m. It will be broadcast from Milwaukee’s Milwaukee Theatre.
