I think the options have stopped being about who is good but rather who is abysmal. I’m pretty sure that’s why Kamala was chosen. No one would dare impeach Biden and eject him from office because it would make Kamala the boss.
It would come down to what the candidate/party was planning going forward.
For Biden, I can’t come up with anyone more bizarre than Harris. The Dems haven’t shown they have any plan for America other than continue to flood illegal immigration across the southern border and to push every plan they can that is bad for America.
For Trump, you can be sure the Dems will continue with their efforts to get him out of office as they will never accept the results of an election where he wins. But I’ve seen some changes in how the Repubs are moving the party. Less moderate, more conservative, RINOs getting booted…but offering people the chance at making something of themselves. That is why more blacks and Latinos are moving towards the Repubs than ever before. As VP he’d probably do well with someone like Ted Cruz or Ben Carson or even Kristi Noem. If he wanted to do like the Dems he could do Kari Lake.
