I think you are catching on.
OK you win. The old adage about arguing with a fool and all...
Just because Cruz is not eligible to be President doesn't mean a fool will accept that fact. Go ahead and vote as you wish. I will not compromise my principles, nor will I vote to set a precedence allowing a future candidate with divided loyalties to become President and continue our path to oblivion.
Your only hope should be that our whole nation is full of Natural Born fools. I think not.
