Early to tell, but I'd give it 60% for the Senate at least. Zilch for the House until 2020 though at the earliest.
Presidential turnout and resentment of GOP Congress will probably sweep out Kirk (if it didn't matter how conservative Pryor was this mid-term in Arkansas, then it doesn't mater if Kirk supports same-sex marriage in Illinois),Johnson, and Toomey.
That's 3 right there, then add coattails tossing out Ayotte, or Murkowski(Miller and Begich run) or Rubio(should be an open seat) and you get up to 4.
We will see as far as 2018 goes, with term limited govs in MI, WI and FL and perhaps recall in IL with Rauner petition, only WVA seems to be gone, minimizing our losses as far as the Senate.
