From what I see Huckabee and Rubio are going after Cruz. They are all fighting for second which leaves Trump free to solidify the top position.
Don’t know what Huckabee thinks he is doing but whatever.
Yes, they are fighting for 2nd. I don’t think there is much to worry about Iowa for Trump no matter what the polls say in January. Iowa usually gets only 120,000 caucus goers. Trump will at least double this number. Trump is on his way to get over 100,000 pledges to vote for him. For Cruz to even complete against Trump, he better triple what Santorum got in 2012, and I still don’t think that’s enough.
