Ted Cruz is not going to be the Republican nominee. Fact.
No, that is an opinion, not "fact". That over 12 million conservative voters have stopped voting over a period of three election cycles is a fact. Like you say (I don't believe you by the way.), I too want the most conservative candidate that can win. Unlike you, I do not believe that the least conservative candidate is the most electable.
The only way to win is to make people believe that there is actually a prize to be won.
The only thing worse than a liberal is a liberal that thinks they're a conservative.
