A serious, non-trolling question for Hillary supporters

I've listened to Hillary speeches, and to Obama's. There's one are where I consistently find Hillary more moving, more convincing. That's on the subject of health care. Compared to Obama, she sounds more earnest, more emotionally concerned about providing health care to all Americans.

But I'll admit I'm cynical about the Clintons. All the more so after the conduct of her campaign, and the negativity of her surrogates and her bloggers.

So serious question here. In her seven years in the Senate, what has Hillary done to bring about health care for all Americans? Is she just using this as an election-year talking point (as so many politicians, not just the Clintons, do), or does she have a track record of sponsoring legislation and doing what it takes to get that legislation passed?

Serious question. I'm not trolling or playing gotcha. I really want to know, so take this opportunity to educate me, with as much detail as you have.
