GS, 90% of Cuban Americans are Republicans and are for the right to vote. What I am saying is if the GOP establishment has a third party candidate to try to have a very small chance of having there way to stop Trump by a house vote for a candidate which may end badly because Hillary still may win since many Republicans may stay home and some may vote for the third party candidate but Hillary liberals will still vote for her and she will win. So the third party will elect Hillary.
I personally will vote for Trump but may not vote the house and senate votes because of there move to stop Trump and because I will know that Hillary will win. I believe that many will do this if they try the third party idea.
A third party idea will have a negative on the GOP establishment all the way down the list(House and Senate).
The best thing the GOP needs to do is back Trump and hope for the best.
