Good points. Trump is still my #2, and there is no #3 on my list.
I started out as Cruz/Trump and decided a few months ago that Trump was better positioned and most likely to take us to the WH - became Trump/Cruz then and started donating to his campaign vs. Cruz's.
Never got a plea from Trump for more cash and can't get the Cruz folks to stop hounding me. There seems to be a slightly different Cruz under the exterior than he has claimed to be and I find it a bit worrisome - won't stop me from voting for him id he ends up on the ticket, but it will be with reservations and as a pure "lesser evil" attitude.
Like you - I have no third choice and I fear that Cruz's efforts may result in another getting the nomination - the delegates going to Cruz are in many cases bought off by others and probably have more loyalty to the GOPE/RNC that feeds those who "make it seem like the thing to do" than they have to Cruz. Perfect storm gonna blow the perfect opportunity, to really shake up the RNC/GOPe, away like so much smoke.
