RNC chair Ronna McDaniel responds to Ramaswamy's resignation call

What she's saying: "Listen, he's at ... 4%. He needs a headline," McDaniel told Fox Business on Thursday.

• "I'm gonna say what I've been saying to Republicans all along: our headline should be about [President] Joe Biden, the border, fentanyl, crime — terrible things that are happening in this country that the American people are looking to our party for solutions, but I also will stand by my record as RNC chair," she said.

McDaniel said that as a federal committee, the RNC was not involved in any of the state election races on Tuesday.

• "I know Vivek is kind of newer to the party. He voted for [Barack] Obama, so he may not know that, but this is something we're going to have to get right ... as a party," she said.

Catch up quick: Ramaswamy called the GOP a "party of losers" during the debate, adding "we got trounced last night."

• The Ohio entrepreneur, citing a need for "accountability" in the GOP, told McDaniel: " ... if you want to come on stage tonight, you want to look the GOP voters in the eye and tell them you resign, I will turn over … yield my time to you."

Zoom out: In order for Ramaswamy to be part of the next GOP primary debate, the RNC said candidates have to poll "at least 6% in two national polls" or "6% in one national poll and 6% in one early state poll from two separate 'carve out' states," such as Iowa, New Hampshire, Nevada or South Carolina.

• Candidates also need 80,000 unique donors, and at least 200 donors from each of 20 or more states and territories.
