What party does McMullin caucus with if he pulls the upset? Still the Republicans? Is there any issue he'd vote with the Democrats on, or is just replacing a lunatic with a Romney type?
McMullin would caucus with and vote like a moderate Democrat, based on his site platform.
McMullin has said that he will refuse to caucus with either party if he wins. My current prediction is almost exactly like the 2020 percentages with Lee possibly winning Grand County due to weird rural turnout in midterms.
That would definitely change if he were to win, which isn't what this campaign intends on doing.
Any senator that refuses to caucus with a party would be powerless off the floor because that is how committee assignments are determined.
