If you voted Republican your entire life but just now decide you won't vote for the republican nominee...then, yes, you are enabling Hillary Clinton. It's not as if you were lifelong democrats. Those we expect, but republicans? deciding not to engage?
#NeverTrump is a republican invention, and it is an abomination.
Consider that if I have voted Republican my entire life, I have voted four times to keep that woman away from any power whatsoever.
Then, there were at least palatable candidates, even if they increasingly did not cause an upwelling of enthusiasm because of their progressively increasing liberal histories. I voted for them knowing full well they would likely not advance Conservative causes enough to overcome the damage already done by the liberal agenda that had slipped through.
This time, the GOP has gone a bridge too far, and as far as I am concerned, they have burned it.
I'm #nevertrump, but I am also no longer affiliated with the GOP. I think you will see more of that.
