Perhaps having Biden pick Buttigieg is the ‘event’ the dems will use to get rid of Biden (i.e. outrage over him not picking a black or a woman). Trying to figure out the left’s logic is a dubious. They’ve done so many things before that seem self defeating. But maybe this is the angle they’ll use. To admit that your candidate has dementia is a bad PR move. Getting rid of him because he’s not progressive enough, not so much (at least to the left and the mushy middle). Perhaps they’re calculating that the combination of the two (i.e. Biden’s dementia and bad VP pick) is the way to go. Relying on only one of those reasons would be politically damaging, but the two together not as much.
All speculation at this point. We don’t even know if Buttigieg is going to get picked.
If Buttgig is picked, this will siphon off whatever remaining black voters there are who weren’t going to vote for Trump or the states where Kanye wasn’t there to siphon off Dem voters. A white homo. Yeah, right.
