In view of the poor record of Mason-Dixon I am not using Mason-Dixon polls. That it gets Minnesota or Wyoming right -- who cares?
Ah ... so you are only using polls you like ?
My prerogative -- and I would reject any pollster with a poor record of prediction or a pollster with a blatant tie to an institution with an agenda. Would you trust an insider poll? A poll by the US Chamber of Commerce or the NAACP? A poll whose patron is a union? Church of $cientology?
The only use for such a poll in my maps is to fill in a gap -- and then if it seems right. I see plenty of junk polls involving Michigan and Pennsylvania.
You can trust that we are going to all see copious polls of Florida.
