What Romney Must Do

David Frum gives advice:

Either directly on the debating platform tonight – or through ads and other media in the days ahead – [Romney] must offer Republicans an advance glimpse of the campaign Barack Obama will wage against Rick Perry in 2012. It won’t be a pretty sight, but Republicans need to know the full measure of their candidate’s vulnerability before they commit to a nominee whose own words (however carelessly and unmeaningly written) will be used as evidence that the GOP wants to repeal Social Security, Medicare, and the theory of evolution.

Stay tuned for debate live-blogging tonight.
