Of the four I’d go with Rubio. Think about Latin American politics. Argentina is gaining libertarian traction just like Poland did with Thatcher in Britain and a polack in the Vatican. Milei got it started and is taking his show on the road. El Salvador is dealing with MS-13 types and Cuba will some day be free. Rubio could throw gasoline on Cuba’s fire and bring the country back into the US graces, minus the gambling and whore houses. Sure he’s a rino but Trump would have him over a barrel should he stray.
He could do worse than picking Rubio, but Rubio’s still a RINO (as well as a resident of Florida). Trump needs someone that he knows will have his back. Rubio might help to increase the Hispanic vote, but Trump is already making inroads into that particular voting bloc.
Trump doesn’t need a VP to help him win. He’s already winning. He just needs to maintain that lead, find a VP candidate who doesn’t hurt him, and won’t undermine his presidency.
