IMO, unless the Rats put up a black or Hispanic for President in 2016, they aren’t going to get near the enthusiasm they had with Obama. A woman like Hillary or Fauxahontas just won’t inspire the low info voters. An old, white guy like Biden - forget it.
I still think think Dems hold the Senate and take the House by 2016 with El Presidente Comrade Hillary.
I seriously doubt any Republican can win with the 3rd party candidate (Libertarians) sucking off even 1% and overcoming the cheat vote. In the past a Republican had to win by at least 3 points to secure victory. I think that number has increased to at least 5 or 6 points. If not the Rats can produce enough fraud to win.
2016 may be the last ballot I cast. Until a radical catalyst occurs I see no point in casting a vote.
