Things that make you go
This friend was a strong Bernie supporter who hate hate hated Hillary during the primaries, although he conceded it was necessary to vote for her after she wrapped up the nomination.
He claimed he hated her because she wasn't progressive enough. But it's hard not to draw conclusions from the difference in the way he treats Biden, given that Biden does not have a more progressive Senate record and on two of the most common criticisms of her, her ties to Wall Street and vote for the Iraq AUMF, Biden has nothing to recommend him. He didn't use to be called the "Senator from MBNA*" for nothing.
Even more
is the nature of the criticism he's defending Biden from, and how he pivots to Democrats being too "MOTHER"-y. I'm sure that's just a coincidence too.
This guy ain't the only one I've seen this sort of thing from...
