Cruz was almost 2000 votes ahead of Bush in NH.
Cruz has 3 delegates out of NH (3rd place finish) to go with the 8 delegates he got for his 1st place finish in Iowa.

It is all about momentum andperception. The last two winners of Iowa were Huckabee and Santorum. Neither became the nominee and neither won SC. Trump will finish one or two in every primary, which makes him a formidable force. Once March 15 starts the winner take all process, Trump will pull away from the field.
