They are critical, but I don't trust any lamestream poll. Trump must have internal polling that shows he's way ahead in WI and MI. There's no reason he would cancel ads if it was neck-and-neck.
Use common sense folks You would not shift millions of dollars to States like Georgia unless you did not have them in the bag.
The polling is irrelevant. It’s going to be close enough and who knows what shenanigans are going on.
