More Ted Cruz. Convinced House Repubs to shutdown the government at the end of last year, and just managed to get House Repubs to not vote for a Boehner border bill that didn't have a chance of getting signed into law.
IF he ran, he'd likely have the backing of the majority of elected officials who choose to endorse candidates (many don't endorse until victory of one individual is clear, so they don't end up backing the wrong person). What I ponder is that Ted Cruz is an extremely intelligent man, and perhaps he knows that he'd be toast if he became the Republican nominee, is if he chooses not to run for President and instead tries to be Kingmaker in return for being named VP. This would allow him to be attack dog which he excels at, bringing conservatives to the polls, while whomever gets the nomination (Christie, Jeb, etc) can stay above the fray and moderate their positions to the public.
