I may change my mind.
I think Clinton's health care plan is better. In the negative column, her campaign has mischaracterized Obama's record in at least one case I know about, repeatedly.
Obama has a better technology plan. He's also got a decent health care plan, just not as good as Clintons. He's brought along an anti-gay preacher to some events to get the evangelical vote.
Frankly, I can't find a whole lot differences, and the only major difference so far is on health care. I'm digging through a few more issues.
