If Trump is robbed of the nomination, and Trump supporters refuse to vote for the GOP candidate, and if there is no viable 3rd party with a path to victory, then, yes, refusing to vote for the GOP candidate would be tantamount to giving support to Hillary, directly or indirectly. Just as you are doing right now.
Everyone is SCREAMING about a contested convention, yet in 2012 Romney was way behind where Trump is now and NO ONE said one word about a contested convention!!! Trump will have the amount of delegates he needs and more!!! GOP-e is creating this hysteria for their own purposes!!! They’re as guilty of dividing this country as the left is!!!! SCREW THEM ALL!!!!
Why is refusing to support Trump now, when he doesn’t even have the nomination, the same as supporting Hillary?
