Biden himself said "It’s no longer about who gets to vote; it’s about making it harder to vote. It’s about who gets to count the vote and whether your vote counts at all." Well in all swing states with Democrats in power, it was Democrats counting the vote and largely making it impossible for anybody else to observe the counting. I don't know how many or if none or all did that honestly but it certainly didn't give anybody but partisan Democrats confidence in the process. If the situation has been reversed and it had been Republicans ejecting Democrat poll watchers and then resuming the counting, you know the Democrats would still be objecting and calling it an illegitimate/fraudulent/stolen election.
Again when I feed my ballot into the counting machine I have absolutely no way (and frankly these days little confidence) that my vote was counted as I voted.
Without accusing anybody of wrong doing, I want a system in place where Democrats, Republicans, Independents, Libertarians, Green Party, EVERYBODY is confident the vote was fair, honest, and competent.
