Time for some idle speculation.
Current frontrunners:
Kari Lake. The failed 2022 candidate has traveled the country, serve as Cheeto's surrogate.
Pluses: Is female and is from a state that Cheeto needs to win in a general election. Plus she regularly pushes Cheeto's "big lie" and whines almost as he does.
Negatives: Isn't blonde. Lost her election. Won't help in the primary, because Cheeto will win the AZ primary which I expect him to win no matter what.
Greg Abbott. The current governor of Texas.
Pluses: Hates people of color and immigrants almost as much as Cheeto. Wins elections.
Negatives: Cheeto will win the general election in Texas no matter who's on the ticket with him.
Others in the mix :
Kristi Noem, the current governor of South Dakota. She's as nuts as Cheeto.
Marjorie Taylor Greene. Currently in Congress. Makes Noem look sane.
Ron DeSantis, currently Florida's Governor and a presumed presidential candidate in 2024. He and Cheeto aren't fans of each other, so if this happens, it will be a cynical move by both.
Tommy Tuberville. Currently in the US Senate. Cheeto likes to think that he's smarter than others. In Tuberville's case, that belief might actually be true.
Gym Jordan. Currently in Congress. His penchant for looking the other way when facing sexual predators may endear him to Cheeto.
Kyrsten Sinema. Currently in the US Senate. A former Democrat who may be as self-centered as Cheeto.
Not gonna happen, either because Cheeto won't have them, or there's no way in hell that they'd take the gig:
Liz Cheney, Adam Kinzinger, and any R who voted to impeach him. Mike Pence.
There will be others in the mix as this early speculation.
