Votes, not vibes, will determine whether Harris or Trump wins in November.
Despite all the doom scrolling, Harris has a comfortable lead in the electoral college right now.
The time for vibing is over. It's too late to change anyone's opinions (especially because national level events like debates are over). Harris will finish her Media Blitz soon (including a Fox News showing) while Trump retreats into his shell hoping no one notices how damn stupid his mouth is.
This is the time for doing. The focus should be on voter drives and other get out the vote pushes. It's mid October, and the October surprises are against Trump and in our favor.
It's not the lead we wanted but it's a lead nonetheless. Don't talk yourself out of believing this lead because of a bad poll or two.
I'd also encourage voting early. It can save you from any issues popping up like getting sick on election day. Campaigns will stop bugging you as much once they see that you have voted (though they obviously cannot see who you voted for)
Though I think early voting is a good thing to take advantage of be aware of your voting board if you're in a swing state. Georgia is making some pretty overt moves that they may try and disqualify mail in votes and call the count early. It's sad that we need to consider this but Trump has already used the "we were winning until they found mail in votes" line of attack and true believers in that bullshit have taken over Georgia's election board.
Early in person voting is also an option. Also it varies state to state when mail ballots are counted. Michigan for instance, is actually going to start counting some of them a bit before the election day as they arrive. (Michigan now has a democratic trifecta in local government)
This is why I (a Georgian) am doing early in-person voting and not mail-in voting. Between the tactic you mentioned, the possibility of disqualification due to a bullshit "signature mismatch," and sabotage from DeJoy (who is still the fucking Postmaster General because Biden apparently hates the USPS as much as he does and failed to make board appointees who would remove him), mail-in voting is unacceptably risky unless you have no other choice. And that's sad, terrifying, and -- most importantly -- fucking infuriating.
