Mike Leavitt on "Co-ops"

I just read this informative article by Utah's former Governor Leavitt. I agree with a lot of what he says. Liberals seem to act like a vote against Obama's plan is a vote against healthcare reform. I can see why they say this, since Obama's plan is the only plan that has any chance of getting passed anytime in the next several years. However, it's not like conservatives are just plugging their ears and saying, "No, things are just fine as they are." Everybody who knows anything about the debate seems to agree that healthcare reform is necessary, but conservatives and liberals have a different idea about how it should be done. I have yet to be convinced by either side, but I'm leaning to the right at the moment. Does anybody have convincing evidence (not "arguments," but actual "evidence") that one side or the other is right? Please post a response if you do.
