Karl Rove made an appearance behind enemy lines last night in SF, at a local gathering at the Ritz-Carlton of conservative bastion The Heritage Foundation. Rove made the astute observation before a crowd of several hundred that the health care debate is providing Republicans with a perfect political rallying point, but it will only succeed if they come up with their own successful plan. No word on whether there were any census workers hanged in effigy, or any fingers bitten off. Hear more about Rove's appearance at KCBS.
