In his most recent column, conservative/moderate/modernizer/No Labels David Frum considers the future of the Tea Party in light of this irony: “After three years of battling against ObamaCare, the most likely winner of the Republican presidential nomination in 2012 is the author of the Massachusetts health care plan that inspired ObamaCare’s basic mechanism.”

To Frum, this is “as if the Democrats of the 1960s had responded to the anti-war protests by nominating Robert McNamara for president.”

A fine analogy, except for the fact that, despite serving as Defense Secretary for a Democratic president, Robert McNamara was a Republican.
