Personal Predictions:
Republicans hold the Senate pretty easily.
House is a toss up. Democrats should have pretty significant gains, but there's a lot toss up races.
Some fun governors races too. I think that Democrats will pick up 3-4 governorships at least. Florida governor going to Gillum (D) is my pick.
As far as my personal voting, nothing really exciting living where I live. Will likely vote R on governor, D on house rep, and R on state senate/house rep.
