It would certainly fire up the MAGA base even more. Question I have is how undecideds/independents would view it.
That being said, I agree with what the article stated that the prospect of him actually being physically incarcerated prior to the election seems incredibly unlikely.

Definitely more likely that some kind of delayed sentence is imposed though, which the Dems would be able to use as a talking point.
