Ever since health care reform was signed into law, it's been clear that much of the legislation's opposition has come from the left, and the latest poll from CNN (conducted Nov. 18 to 20 with margin of error of ±3%) shows that nothing's changed:

And while 23 percent of liberals don't think the bill was liberal enough, it's not just liberals who think the bill should have gone further: 35 percent of moderates who don't support the bill think it wasn't liberal enough.These kinds of numbers illustrate the why the Republican tea party approach—simply repealing the bill and going back to the way things were—will probably never happen. Even though a majority of Americans oppose the legislation as written, it's also true that most Americans either support the bill or want to see it move in a more progressive direction. And the way that will happen is by building on health care reform—not by destroying it.
