Part of why I voted for Obama is because I knew he could sell anything. He has a way with words. Not only that, though, he persuades by appealing to our higher-order thinking. This most recent example is refreshing and on point:

If private insurers say that the marketplace provides the best quality health care; if they tell us that they're offering a good deal, then why is it that the government, which they say can't run anything, suddenly is going to drive them out of business? That's not logical, they should be able to compete.
