I feel a lot more confident about the 2012 than the 2008 election. From what I saw, most citizens could not discern the difference in either candidate in 2008. There is a clear difference in 2012 and the average citizen must admit that under the Democrats their net-worth imploded, there salaries went down, along with their lifestyle.
There is also the question of when these "scientific" polls are conducted. If they are conducted during the 9-5 working hours, then just who are they polling? Either slackers or non-productive citizens at home instead at work. I doubt the veracity of the polls under these conditions.
I can't wait till November!
