I'm supporting McClintock because he represents what I believe in more closely than Arnold. If he urges me to vote for Arnold, I likely will.
If I believe that my single vote will sway the election to Cruz I will vote for Arnold. If I think Arnold is going to win, I will vote for Tom.
I will have it both ways, dammit!
And if that comes down to choosing between someone much worse or someone who will compromise the soul of the very Republican Party which is tainting itself to win, I'll vote to keep Davis.
