Her tenure as a Senator and as Secretary of State have no glaring failures that define her time in those roles.
Are you serious? The World is going to shit and she oversaw four years of our foreign policy. Russia is annexing parts of her neighbors, ISIS is on the march, China is bullying her neighbors, North Korea still has nuclear weapons, Iran may yet obtain them, and she was one of the biggest cheerleaders for regime change in Libya. That's just her list of "accomplishments" as SecState; wanna talk about her time in the Senate? Two words: Iraq AUMF.
I'd say her entire record as Senator and Secretary of State is a glaring failure. Why don't you proffer something she did right instead of saying she didn't completely fuck up?
