I think Hillary should drop (1) because of their reasons and (2) because she seems to always lose to Obama lately. Not to mention that even if she isn't sucking as bad as I think she is, I still don't think she has good temperament and decision-making skills as Obama. She'd be a great Vice-Presient though, I think.
Otherwise, she's so stubborn and head-strong and loses her cool too much. She just....shouldn't be president. Period.
I'd love to be proven wrong because it means a great 4 years, but I really don't think she's best for the job. talk2hand
