Albeit anecdotal evidence, our precinct had a majority of Methodists, with just a couple of us "holier-than-thou" Baptists in attendance. Methodists tend not to be evangelical, but would consider themselves pretty "middle of the road," at least compared to us fire-and-brimestone Baptists.
(Man, I hope I didn't start a cross-town war between the churches with that statement.)
Point is: People voted for Huckabee because they don't want some east coast plastic banana FM type telling us ya-hoos in the sticks how to live our lives. We want someone that we can relate to, that is approachable, and seems to have solutions to our country's needs. Mike Huckabee has the experience and leadership to get the job done.
We didn't have to consult with Rush Limbaugh or Laura Ingraham before making a decision. We didn't refer to Bob Novak because we don't take the New York Times; The Des Moines Register is bad enough to tell us that newspapers are on the decline. We carefully looked over the candidates and picked the one we thought would serve us best.
See, we don't require talking heads to tell us what to think or do. We don't receive marching orders via Fox News.
We Iowans are a surly, independent bunch.
