They don’t have to bother. Trump’s insane attack on what he perceives as his GOP rivals (including DeSantis) just two days before the elections did that for them.
I honestly think Trump’s sudden irruption into the process confused voters and in fact did dampen the turnout for some GOP candidates, as well as reminding people who never liked him anyway that he was still out there and still going to be attacking other GOPers on a very personal basis.
I think the GOP once again will end up fighting over who is pro-Trump, who is anti-Trump or who simply doesn’t want to get involved with either side but actually thinks we should just concentrate on policy and positions.
You will be voting for Trump in Nov. ‘24.
Get used to the idea. Where else are you going to go?
