I imagine in this case there’s a little more to it, namely that incumbent presidents overwhelmingly win a second term. The last time a sitting President failed to do so prior to Trump was all the way bac in 1993.

I don’t like Biden, hell, I don’t like electoral politics; but it’s probably wise in a party-political sense.

They seem to have believed he was just attempting to win over Trump supporters for the nomination; but trying to outdo someone who, to a large degree, sets the agenda for what their base supports and cares about seems blatantly fruitless and silly, to phrase it kindly.

(Now he’s failed to secure that support and alienated the people who liked him for not being Trump, lol. Poetic in a way.)

Sadly the pickme mindset is not limited to gender.
