What I see in that map are a whole bunch of blue states chock full of moderate Republicans who don't post on Free Republic, but who do vote in primaries.
Purple and green; Gingrich and Santorum. Cruz needs all that combined and he'll still have less than half the delegates Romney earned.
The reality of the situation is he is going to have to sell the Cruz brand to a whole lot of orange squares that said no to Gingrich, no to Santorum and yes to Mitt Romney.
A lot of that orange had no choice in the matter since the primary had already been decided by the time they had a chance to vote.
Like I said, it's a lack of a GOOD conservative candidate. The last time we had a GOOD conservative candidate was Reagan. The map would have looked the same in the prior election to 1980, but Reagan, being a GOOD conservative candidate won the hearts and minds of the squishy GOP voters with his ability to communicate, and then the country.
Cruz has the capacity to do the same.
