Sure, the danger will not entirely go away, but it will be crippled severly, giving us a chance to rid ourself of more fascists (basically the entire GOP at this point). There is already a lot of infighting and people already resign from congress. Its likely the GOP will loose their majority because of that.
Trumps legal cost is draining conservative coffers and he fleced his voters on every turn.
The party lost big donors, specifically because of the ever increasing reality-disconnect Trump is forcing. He is just a to risk, investment and black hole for funds.
When it comes to it, the trumpian playbook just reads "be Donald Trump" and no one else is that.
No other know candidate comes close.
DeSantis is barely human at the best of days. Haley is a women, a negative for the sexist GOP.
They went all in now on MAGA to mobilise their party in ever dwindeling chances of getting elected again. Turns out if you are a ghoul, hate humans and let that mask slip (Roe for example), you wont get votes and loose support.
