Why should I vote?

This issue has been discussed before here on NB, but I wanted to get some fresh answers.

I have been voting for many years, but in this election I may refuse to vote in the general election if any of the RINO's get the nod at the convention. Unless you have never heard my reason why, here's a brief. The RINO's in the GOP have nearly gutted a once proud political party and I refuse to give them my vote. This is not a matter of me abandoning the party, because the party has already abandoned me.

So here's my assignment to you. Give me your best argument as to why I should vote for a RINO if they get the nod. I have heard all I can stand about "if you don't vote for one of these guys then Hillary will win the WH", so please leave this one alone.

In case you are wondering.... Fred is my 1st choice, Duncan my 2nd, and there is no 3rd.
