How many people think Harris is merely a place holder?
What are the chances that she "drops out" for one reason or another before the election and causing even more chaos?
How late in the race could Michael Obama be pushed?
If she unexpectedly drops out 3 days before the election.....total chaos
Which is why it's plausible?
One problem. The ballots will have already all been printed across the nation (they are being printed now, and some states mail them out the first week of October - 6 weeks out from now). You think Big Mike can win as a write-in? Otherwise they would have to delay the election date to reprint ballots and get them distributed. I also find it hard to believe that Harris/Walz will be on the final ticket, but there isn't enough time at this point to make a change.
