John Fetterman is not an FF. No-strings-attached money to a foreign government that is, at best, neutral to American interests at the moment, is not a mainstream Democratic opinion. Most Democrats (like myself) wish for restraint in Gaza even if they agree with the overall military mission and are critical of the current far-right leadership. He is also incredibly dismissive of his constituents and their concerns on a variety of topics. His wife is going to leave him soon because of the pro-Bibi extremism.
My selection will be Arizona when Pixie Cut Manchin is gone, Qari gets sent to the shadow realm in November and it's Hobbs, Kelly, Gallego.
Kari Lake will win.
