Vote anyway if anyone hasn’t yet. Because no matter if it’s close, a few points, or a sweep Trump is already planning on calling it rigged (he already has) and rallying his supporters to do who knows what. It’s going to be a long few months, maybe more.
The larger Harris' margin is, the harder it will be for the GOP to steal. If Trump loses a state by 5 votes, it'd be easy to "find" five "irregular" votes and discard them. If Trump loses a state by 500,000 votes... they're not gonna find an excuse to toss that many. Nobody outside the 30% deplorable contingent would believe that for a second.
"Always Republican leaning" is a kind of reliability.
