The president is just the #1 actor on the political stage, while the Producers and Directors who really determine what the actors will do and say on the stage are behind the stage and they are not from election.
So, take it easy - it is a show - just pick up one that looks good, talks humor that can let you laugh Don't count the president to change the course of the ecominic (any real issues) - that is not his/her job and he/she has no power to do anything significant. All the president, togethor with Senete and congress, can do is shift the distribution of wealth a little bit throught tax bills, etc. But that shif need to be within the toleration of big bosses, these who behind the stage. If you look for the president to make any significant change on the real issues, you will be disppionted for sure - wrong place to look for - like trying to catch fish on trees!
That said, the only thing be careful with is NOT vote for someone who will do more harm to you (if you belong to the general public, not one in the interest group) and society than the other guy. IMHO, Romney is the one will do more harm. The reason - Romney and his family belong to the interest group, and he is absolotely surrounded by interest groups. Of course, if you belong to interest group and have some connection Romney, that would be a different story - if you support him and I am sure he will give you nice return if he become president.
