Well, a Democratic president can't do much with a Republican congress, so Obama won't do anything. Now with a Republican (Mitt Romney) his bills will more than likely pass, but those bills might not be good at all. So, if Obama get's elected the congress will still have control. If Romney gets elected, he will more than likely be able to persuade the the congress because he is a Republican.
Now, personally I wanted Gary Johnson to win or Ron Paul, that didn't happen so I really don't have respect for either of them.
I also forgot to add, Romney as of now is winning the electoral votes 88 - 78. This could be another Al Gore kind of thing where Romney has the popular vote, while Obama has the electoral votes which of course are obviously more important. May I also add that Romney is winning the popular vote by 3%.
