They are both bad, Obama is a better person than Romney but he has made some highly questionable decisions that threatens the liberty of the citizens of the USA, Romney has some seriously crazy views imo.
You know, nobody's perfect. You have to think whoever's doing that job is trying to do the best, no matter if the person is called Bush, Obama or Romney. I'm no expert on the candidates but all I really need to know is that Obama moved the US out of times where only people with money were allowed to be healthy and Romney is a homophobe. Easy decision in my opinion.
