The problem is that Huckabee is going to bleed evangelical support from Cruz. And guys like Walker and Paul are going take away blue-collar and libertarian support away.

I don't see Cruz winning the nomination. Therefore, my write-in vote goes to Governor Palin.

Huckabee has been pretty invisible so far. Does he have any dough? That’s what it’s going to take to compete with Jeb.
The Cruzer has enough smarts to realize this may well be a financial marathon with him, Trump, and Jeb fighting a long long battle.

Huckster is tanking in campaign funds.

His magic Diabetes tonic isn’t selling well.

I don’t think Huckabee has that much appeal.

You're looking at this perhaps the wrong way. What you could also say is that Cruz will get some support from evangelicals, libertines, economic conservatives, small government conservatives, national defense hawks and pro Israel conservatives. He has the widest swath of appeal of anyone. Huckabee's going no where, ditto Paul, but yes, Walker is going to be formidable.
