there's nothing that a kamala harris or a cory booker can do to squeeze out of this, either. if you're kamala harris, you have to sweep the south - that's how you win. so, you have to beat cory booker. and vice versa.
what i'm getting across is solely a tactical consideration. the south is a problem for the left, because they skew towards conservative value systems. and, i'm just being realistic about something that the field won't openly talk about; the tactic for decades has been that you do your pilgrimage through the black churches, gnash your teeth at the social conservatism and gun culture, and hope it works out - all the while trying to avoid saying something that's going to make you sound like a hypocrite to your base of urban liberals.
this has not helped the left achieve it's goals. it has not helped the democratic party. and, it has not helped the united states of america.
the ideal would be to leave the south behind, but you can't. except, now you can.
most of these states are not going to be in play in the general. there's no broader value in winning the south in the primary; it's just a distraction from the more important battle ground states in the midwest.
if you can get the centrist candidates into a protracted fight in the south, that just frees up resources to fight in the midwest. and, as i say - if they're black, they can't avoid that. to them, this is the only strategy they have, and they know it.
the left needs to know that the only strategy it has is to abandon the south, and the only way it can do that is to split the vote. so, it should count it's blessings and get out of the way....
