What shift? I like Ron Paul, I agree with him on many things. But he clearly was not going to have a real chance in the election. I also agree with Obama on several issues, realize that his charisma and personality can be a great asset towards realizing some of his ideas, and knew he had the best chance of success (something I've been saying he had a serious chance at since 2004). I like and support both guys, but put my efforts and vote behind Obama.
Don't worry, Nightwing, I will make sure to repeat this as many times as needed for you.
