Those that already hate the Bidens are going to hate them more.
Those who support the Bidens, are going to convince themselves that these are just dirty tricks by the Trump campaign and will be determined to vote for Biden just the same.
In other words, this will not move the needle much election-wise. The caked is baked already with regard to the election.
But if Biden somehow wins, this is clearly not going away and will serve as a premise for the Democrats to quickly get Joe out of the way and plug in Kamala (with a handpicked VP that will do their bidding).
Basically this is how the "coup" will go down.
Fortunately, I think Trump is going to come away with a solid victory Tuesday night. Then the Bidens and their ilk will really have a lot to fear.
I hope and pray that your last sentence is correct.
I suspect if Biden wins, he’ll step down voluntarily. He’s only running to render himself immune from investigation as a “political rival.” Remember, he announced his candidacy 4 DAYS after Trump’s first phone call to the new Ukrainian president. I’m positive that’s not a coincidence. He doesn’t want to be president. He just doesn’t want Trump investigating the Obama/Biden administration.
