Regarding Georgia, the Secret Ballot will again prove those polls wrong. Remember election night how they wouldn’t call Georgia for Trump until almost mid-night or something? Wasn’t even close, Trump won by 5%, yet they were sure Hillary was going to take Georgia.
I live in Atlanta and the metro area including the burbs is getting more Democrat. Lots of transplants from the north and west and a bunch of db millennials as well.
Don’t forget, many of those “Democrats” they sampled are mainline Dems who are horrified at what their party has become. They don’t want to change to the party of Weakling Pansies Jeff Flake-wannabes, but they love and admire Strength and Courage, which is embodied in Donald J. Trump.
