According to RCP average in Iowa, Santorum is at 0.5% in Iowa. This is very low considering he won the Iowa caucus, and 10 other states, just 4 years ago. Does anyone think that Santorum could surprise us all and perform better in Iowa than what is expected, maybe in the top 5 slots? I don't think he'll win, but I think he may surprise us when Iowa results come in. If you think he'll perform as low as the polls suggest, why do you think that is? This would be a massive drop of support in just 4 years time, conventional wisdom would say that he would at least do better than 0.5%.
Well he is irrelevant this time around, maybe at max he'll get 1%-1.5% tops, but 99% of his support has gone to Cruz most likely or back to Huckabee.
