Biden is the most sane candidate they have.
That’s not why he is likely to get the nomination.
Whoever gets the nomination will lose to Trump and damage their brand.
I suspect most democrats want their candidate to do well but come out second in the primaries.
I suspect any Democratic presidential candidate for 2020 who is under the age of 55 is actually running now to be the front-runner in 2024.
They don't have a sane candidate. Biden is in the middle of the pack of their collective insanity. Creepy, stupid, bad memory, daily gaffes, wrong on every possible issue all his life, can't string a sentence together.
That's not a picture of sanity....
