David Corn wites at Mother Jones:
It's no secret that Mitt Romney has an albatross around his neck: Romneycare, the Massachusetts health care overhaul he enacted while governor of the Bay State.
The plan, which included a mandate compelling state residents to obtain health insurance, was a model in part for President Barack Obama's health care reform, which is much-despised by conservatives and Republican voters.
This video of the Romney-Kennedy healthcare bill signing, in which Romney introduces "my collaborator and friend Sen. Edward Kennedy," will make defense of Romney as a constitutional "conservative" that much more difficult. And it should.
