Top candidates for Kamala Harris’ running mate position.

After being endorsed by outgoing U.S President Joe Biden who dropped out of the 2024 race Sunday, V.President Kamala Harris appears to be closing in on the Democratic nomination, after triggering a rushed competition among the Democratic Party’s rising stars to become her running mate—with multiple names circulating.

According to CBS, Harris’ team is vetting about a dozen people, including Governor J.B Pritzker of Illinois, Commerce Secretary Gina Raimondo, Transportation Secretary Pete Buttigieg and Kentucky Governor Andy Beshear.

The following is a full list of heavily rumored runningmate candidates for the Vice President.

Cooper and Harris have stumped for Biden in Cooper’s home state, which hasn’t picked a Democratic president since 2008 but is typically close, and he spoke to Harris over the phone Sunday, he told MSNBC on Monday.Shapiro, who like Harris, previously served as his home state’s attorney general and fought lawsuits from former President Donald Trump and his allies challenging Biden’s 2020 win in the state, could help shore up support in a must-win Rust Belt state for Democrats.

Kelly also represents a swing state Biden narrowly won in 2020, and he defeated Trump-backed Republican Blake Masters in the 2022 midterm to help Democrats maintain control of the Senate—the former astronaut and husband of former Rep. Gabby Giffords, D-Ariz., tweeted Sunday he “couldn’t be more confident that [Harris] is the right person to defeat Donald Trump.”

Whitmer could also help the party win votes in a key swing state, but she said Monday she would not accept an offer to be Harris’ running mate.

Walz, who chairs the Democratic National Convention rules committee, told CBS Minneapolis affiliate WCCO on Monday becoming vice president is something he would “be a little nervous about.”

Kentucky’s popular governor, Beshear, who has won his deep-red state twice, is another potential pick for the No. 2 spot on a new Democratic ticket, though Democrats would still be unlikely to win Kentucky.

California Gov. Gavin Newsom, Colorado Gov. Jared Polis and Pritzker are other names commonly floated, but they could be at a disadvantage since they represent blue states, while Raimondo—who served as Rhode Island governor—is also reportedly under consideration.

Sen. Amy Klobuchar, D-Minn., and Buttigieg (who both endorsed Harris) are other potential candidates who have national name recognition from their 2020 presidential campaigns.

Sen. Raphael Warnock, D-Ga., if chosen, could also draw Black voters in the key swing state, where he’s proven he can beat Republicans—twice—in closely contested races, but if he leaves the Senate, his state’s Republican governor would pick his successor.

Maryland Gov. Wes Moore is another rising star in the Democratic party, but he said Monday he has “no intention” of leaving his current role.
