New poll by Research 2000 for DFA and the PCCC shows that people hate the mandate:

Would you favor or oppose requiring all Americans to buy health insurance — the so-called mandate — even if they find insurance too expensive or do not want it?
FAVOR OPPOSE NOT SURE
38% 51% 11%

I’d also note that the wording of the question is the most charitable rendering the issue is ever likely to get.

When it appears in the ads of a Republican challenger who notes that the IRS will act as Aetna’s collection agency, I bet those numbers get dramatically worse.
