When averaging the three states, Cruz is third
Yes third with 8.3% but Trump is first with 35% which means that Trump has over 4 voters for each Cruz voter. I just do not see Cruz catching up with Trump. Iowa is Cruz best state and Trump is beating him there with ease. I also think Trump support is being under counted. The pollsters are polling likely Republican voters but Trump has a great deal of cross over support that probably is not in the likely Republican voter bucket.
