In Iowa, which is the state the article is discussing, Huckabee won the 2008 caucus; Santorum won 2012. One would assume that they have better name recognition than say, Gilmore. Trump's been a celebrity for decades. Maybe I'm being naive/idealistic/whatever, but if I was being asked in a political poll who I was voting for, and I'm so low information that all I have to make a choice is name recognition, I would pick Huckabee or Santorum because I should recognize their names as politicians.
