Is now the time for moderate Republicans to try to retake control of the party?

Which “moderates”? Mitt Romney, your only named example of a “moderate Republican”, does not seem to be in any way “driven towards Trump”, and nor does Liz Cheney. You say that moderate Republicans can be found at The Dispatch, a self-described “conservative” Substack publication founded in 2020 by anti-Trumper conservatives who also show no signs AFAICT of being “driven towards Trump”.

So who are all the actual Republican “moderates” who are being “driven towards Trump” by the DoJ pursuing their investigation of his possible crimes? We can all see that a bunch of decidedly non-moderate loony Trumpist conservatives who were getting a little bored with ex-President Trump’s lowered profile are now gleefully re-energized with a bunch of new and revived wackadoodle conspiracy theories about Trump being “persecuted”. But those are presumably not the “moderates” that you’re telling us there are “lots of”.

Can you cite which commentator you’re referring to?

Do you want the US Attorney General to just give up pursuing investigations into possible serious crimes on the off chance that that will result in Donald Trump magically just “going away”?

That didn’t seem to be your attitude towards FBI investigations of possible serious crimes the last time there was a similar sort of kerfuffle.

Posts and posts in 2016 amplifying and analyzing all the hypothetical suspicions about the FBI investigation of Clinton possibly turning up evidence of serious wrongdoing.

A couple grumpy laments in 2022 that the FBI investigation of Trump’s potentially far more serious wrongdoing is misguided because it’s somehow interfering with the alleged likelihood of Trump just “going away”.
