The early donors to Jeb Bush (I warned them) have panicked and realize they flushed their money down the rat hole. Now, they are searching for another R politician they can buy. They will need to blow a lot more cash before they can grasp the reality that any candidate they can buy will either have to flat-out, convincingly lie about the positions he supports or will not be able to get the necessary votes to win. Tough situation for them, after buying so many candidates over the decades, but not my problem.
Bush isn’t toast until Biden (or another prominent Dem) enters the D primaries.
While there is a lot of talk, it hasn’t happened yet.
