Ted Cruz, unlike Sweater Vest and Huckleberry, has money in the bank and a nationwide organization.
Since 1976...Except for 2012, 2008, and 1980... Iowa has voted for the eventual GOP nominee.
In 2012 Santorum actually got a 34 more votes than Romney.
In 1980 George H.W. Bush won Iowa over Reagan by about 1.5%.
Of course there were years that a sitting president was running unopposed.
So from 1976 until 2012, the eventual GOP nominee has won or finished a close 2nd except for 2008.

So it is important to do well in Iowa.
Glad to see Cruz moving up!
