I honestly think that's exactly what the Democrats had in mind in February 2020 when they had all the other contenders drop out in favor of this feeble retardate in the White House now. Up through Super Tuesday in early March they were convinced Trump would win.
The Branch Covidian hysteria that began just days after that was what changed their mind. I have a hard time believing they'd pull out all the stops in 2020 just to get this loser elected.
Except, I actually think all the other Dem candidates in 2020 were dead ends. Certainly Kamala and Liz were.
