Here's the Wall Street Journal's headline on an op-ed by a trio of conservative activists:

Health Care Is Hurting Democrats

New polling data show that voters know exactly where candidates stand.

And here's their explanation:

How do we know that it's the health-reform bill that's to blame for the low poll numbers for Democratic Senate candidates and not just that these are more conservative states?

First, we asked voters how their incumbent senator voted on the health-care bill that passed on Christmas Eve. About two-thirds answered correctly. Even now, long before Senate campaigns have intensified, voters know where the candidates stand on health care.

Wow. That's totally not what “voters know exactly where candidates stand” means. The three found that “about two-thirds” of votes know whether their Senator voted for or against the health care bill -- but that's far, far different from knowing what is and is not in that bill. Voters don't “know exactly where the candidates stand” simply because they know how the candidates vote; they also need to know what that vote means.

Put another way: A voter who thinks the health care reform bill contains Death Panels and would outlaw private insurance but knows that Harry voted for the bill is, under this construct, a voter who “knows exactly where the candidates stand” -- even though he is, in fact, completely wrong about where the candidate stands.

That's obvious nonsense.
