How is health care polling in those key swing House districts? Well, as lousy as you might guess.

The Start Over! Coalition – a group of 248 employers – contracted the Tarrance Group to gauge support for the health-care bill being debated in Congress. On March 7 and 8, they surveyed 300 likely voters in each of 11 key congressional districts. As you would expect, its popularity ranks somewhere between Tiger Woods and Toyota accelerator pedals.

The numbers show ominous news for House Democrats Gabrielle Giffords of Arizona, Betsy Markey of Colorado, Baron Hill of Indiana, John Adler of New Jersey, Steve Driehaus and John Boccieri of Ohio, Dina Titus of Nevada, Mike McMahon of New York, and Jason Altmire and Chris Carney of Pennsylvania.

The highest level of support for the bill is 40 percent, in Titus and McMahon’s districts; even there, opposition runs 52 percent and 46 percent, respectively. The lowest level of support is in Carney’s district, at 28 percent.

Opposition is pretty strong across the board, lowest at 46 percent in McMahon’s district, highest in Markey’s and Carney’s districts at 58 percent.

Voters in every district said the vote would be “very” important to their decision this November, ranging from 63 percent in Giffords’s district to 81 percent in Altmire’s district.

While the sample size is a bit small, there’s not much reason to think this poll doesn’t catch the public mood fairly accurately.

Last fall, Giffords, Hill, Driehaus, Titus, and Carney voted “yes”; Adler, Markey*, McMahon, Boccieri, and Altmire voted “no.”

The firm also polled the district of Michael Arcuri of New York, who has since indicated he will vote “no”; 32 percent support the bill, 53 percent oppose.

* I originally misread a chart and had Markey as a “yes” from last fall.
