McCain or Obama?

I know, I know, three posts in one day! whew! I guess I just have lots to say.  So, I still don't know who I am voting for!  Who are all of you voting for and why?  My sister has pretty strong arguments for Obama.  Any pro McCain's out there?  I need your political advice! I have read a lot and learned more about the candidates this year than ever before, yet I feel like the more I learn, the harder my decision is to make.  Now, I know all you PG'ers are voting for recycling, but what about our president?
