Democrats should run someone credible like a state legislator to run for the Green (or Mountain if it still exists) Party nomination and give them enough money to run ads. Better to throw the election to a generic Trump Cultist than risk letting Manchin win again
Horribly disagree if we're ever going to win the majority back anytime this decade. I'm displeased with him, but let's face it he is a hundred times better than any Trump cultist pack who would otherwise win. It's West freaking Virginia.
I suspect he will lose by somewhere close to double digits, but God bless him if he can at least make it erase requiring Republicans to put resources into, or possibly even pull off a minor miracle and win.
