Colorado is in the bag. Imo. So is Alaska and Arkansas. Louisiana and Iowa will fall next. Add in Montana, West Virginia and South Dakota, and that’s 8 seat steals.
Allowing a loss or two in Georgia Kentucky and/or Kansas to get +6 needed.
It is unwise to make that assumption.
Boulder and Denver counties will certainly vote the Democrat ticket. There is also the prospect of substantial vote fraud in both places, which could inflate Udall's total showing.
It's not over until it's over.
