Over at Contentions:

The New Republic’s Jonathan Chait continues his indefatigable political defense of ObmamCare. One of his recent efforts, “Health Care as Political Scapegoat,” can be found here. He writes, as proof of his thesis, that “a recent Gallup poll shows that Democrats fare about evenly (+1) versus Republicans on health care — it’s one of the only issues where they don’t have a disadvantage.”

Now what might be missing from Chait’s analysis? Context.

As I pointed out here, in October 2006, the Democrats held a 64-percent v. 25-percent advantage over Republicans regarding health care. Today the lead is 44 percent v. 43 percent — a 38-point swing in favor of the GOP. That is a substantially larger swing than we’ve seen on combating terrorism (29 points), the economy (27 points), and handling corruption in government (26 points).

There is no other issue, in fact, over which Democrats have lost as much ground as quickly as over health care….
