I don't know exactly what they're doing, but it's not a good sign that I always know what a Trafalgar Group poll is going to say without having to open the link.

I'm not a Let's Delve Into The Crosstabs guy, but some of the shit here is just crazy. Trump is not going to win 30% of the Democratic vote in Michigan. Biden is not going to win 25% of Republicans.
