May I be honest in this forums? I'm quite frightened for Hillary 2016, I personally have no reason to trust her just as I have no reason to trust Obama. I like to call myself a libertarian-left and usually hate big, oppressive governments like what Obama is running now, but don't worry I'm no anarchist.
Part of the reason I reject supporting Obama is that while people love him and his party for progressive ideals (such as gay marriage, marijuana, etcetera) people are often ignorant of his more...oppressive policies such as the NDAA, kill list, drone wars, etc. and with this I have no liking for a government that kills innocent men, women and children, sorry to put it bluntly.
I don't think Hillary would be any different considering she is pro-war, believes that the biggest victims of war are women and children who have lost husbands, and laughed at the death of Gaddafi (never liked him anyway but I could never imagine laughing about it), etc. I think my biggest concern is people voting for her because they think it will be "progressive" and be totally ignorant to her flaws and bad policies like most Obama supporters are.
Not trying to offend anyone, I'm still young and have so much more to learn but I thought I'd put in my two cents.
