This is the elephant that many don't want to face. If the base won't turn out for Romney against Obama, what makes anyone think they will for Trump against Hillary? The lesser of two evils theory has shown itself to be unacceptable to evangelical voters.
The "base" can't elect anybody on it's own.
The issue is (assuming you believe Trump would be better than Hillary, as I do), can Cruz or Trump attract more non-base votes? 69 million Americans voted for Obama. A winning GOP candidate needs 10 million of those votes.

Amen. Unfortunately, neighter the GOPe or this “Trump movement” can grasp this simple truth.
