Trump will have to use the power of Federal law enforcement in some way to counteract that. He has been reluctant to do so up until now - we can hope it will be his October Surprise.
Trump knows this and is on the case, if every any candidate was on a case.. Attempts will be made to beat DjT because Ds believe everyone hates him, so no one will mind if they cheat in favor of the “good guys.” Extremely dangerous attitudes.
Trump knows. Counter actions are in place.
We know law enforcement will be on call if poll intimidation pops up. I expect legal threats if there’s discrepancies like those just exposed in Michigan.
Some of the states may get away with ballot harvesting, (which will be legislated as illegal in the new R Congress), but will have limited affect now that we’re wise to the scam. Little worry, I hope.
I do worry about some swing districts, as in California, that were stolen via ballot harvesting in ‘18, but again, we’ve been forewarned. I assume Rs are planning on ballot harvesting, too, where legal.
