Why would he oppose it if Tumpy has already got a deal on the table to surrender? Because its the ethical and necessary thing to do if we're to stop this desecration of the rule of law.
Why in hell would you think he should dirty his hands? Especially for a guy who is out there talking smack about him every day?Because doing what's ethical is not based on liking someone, nor is it based on the whether or not the actions of the other person have hurt your feelings. Doing the right thing is a moral imperative and action is dictated by the injustice that is occurring...Desantis has the ability to fight an abuse of our legal system, and thus an obligation to do so.
Ethics aside, stepping in is a strategic imperative. If he wants to win in 2024, it IS required. From a strategic view, he cannot win without gaining substantial support from Trump supporters. Right now, he has a chance to do so...but this moment will pass quickly. If he does nothing NOW...he will never have another opportunity to regain that support. I'm not speaking hypothetically, though perhaps anecdotally, when I say Desantis cannot afford to do nothing in this situation. If that's his tactic, he loses 15-20% of GOP voters...including me. As a bonus, standing up can help him with Independents as well...who mostly understand what a witch hunt looks like.
