See now here is where fights can be started. I will be supportive of Trump/Cruz and will push them but if the Republican voters select Rubio or someone else I will vote for the nominee. Its up to us conservatives to get the conservatives elected by turning out and getting our friends and followers to turn out. If we cannot do that we have no one to blame but ourselves. Staying home is a vote for President Hillary and its something I can never or will ever do.
There is nobody on that debate stage that I would not vote for over Hillary Clinton. And that includes Rubio.
However, before I did, I'd have to check out the third party candidates.
