Tomorrow is Election Day

I mailed in my ballot on Saturday. This election has come so quickly. Hopefully Tuesday's results will lead us to four more years of Obama, and in California: GMO labeling on our food, more money for education, and no more death penalty. 

One voter guide I used to help me in my decision-making:

I'm sure we must, we can, and we will eventually change our two-party system, but I voted for Obama because I don't think that it can happen in this country from the top down. Is it possible to convince enough people to elect a Green Party or Independent President before there's a significant presence in the rest of our government?
