Opposing Health Reform: Bad Politics?

A new TV ad from Americans United for Change flashes forward to November 2010:

For a while now, it's seemed that moderate Democrats are the ones at risk of losing their seats for health reform "yes" votes. Then again, the Washington Post/ABC poll published today found, among other things, that intensity gap is closing, with 30 percent "strongly" behind President Obama's push for reform, vs. 36 percent "strongly" against it...so maybe things are changing.
