Even though Harris kicked Trump's butt last night (and got Taylor Swift's endorsement), there is much work ahead:
1) You're right, its all about the swing states (mostly WI, MI, PA). These states may be swung by heavy black turnout in Milwaukee, Detroit, Philly, or by an upsurge in young voters.
2) Rogue Repubs are trying to trim voter roles, poised to "not certify" close votes in some counties
3) Pro Palestine Jill Stein may help Trump by bleeding off Harris votes in Muslim-heavy Detroit area.
4) Many believe a more centrist PA Shapiro would've been a better running-mate choice, as PA is the big prize. However, Walz seems to be energizing young progressives.
5) CNN focus group of independent swing-state voters last night didn't seem to notice that Trump got whupped...and that's what worries me.
6) Harris/Walz may need to get "more manly" to win swing states (ie more pro union, pro oil, less LGBT talk)
