A little Iowa perspective:
In 2008, Romney got 25% of the vote.
In 2012, Romney got around 25% of the vote.
In 2008, Ron Paul got 10%.
In 2012, he got around 21%, more than doubling his support, while Romney remained stagnant.
In 2008, Paul lost Iowa by over 20%.
In 2012, Paul lost by about less than 4%.
Paul is dominating among the under 35 vote.
There's a lot of of win in there. Maybe not Charlie Sheen winning, but definitely some win
