What happens if Democrats succeed with universal healthcare?

Kos tells the story of a woman he met in Austin who was convinced that elected officials can't do anything about problems like health care or the mortgage crisis:

[...] Well, I responded, what about health care, are you happy with your health care? She lit up, "I know no one who is happy with their health care!" and then segued into a rant about the disgraceful state of the health care system. Well, I responded, Democrats are working for universal healthcare, but Republicans have gotten in the way. But we'll be able to do it next year.

"Ain't no one who can fix that stuff," she sighed, slumping. That brief expression of fire and brimstone snuffed out in an instant. She was adamant that it was all hopeless. [...]

I had one last argument up my sleeve. Look, I get it, I told her, government hasn't given us many reasons to be confident of late. I can certainly empathize. But can we make a deal? If Democrats push through universal health care in the next four years, will you vote for Barack Obama in 2012?

She looked initially uncomfortable at the thought, but after a pause and a brief internal struggle, she softened and said, "Yeah, I will."

That, in a nutshell, is what Kristol and Ponnuru and Lowry and every conservative in this country fears the most.
