Frum’s top pick is Heather Mac Donald, Harvey Mansfield suggests our own Victor Hanson or Jonah, Grover Norquist suggests Fred Barnes, Rod Dreher suggests Ross Douthat, Patrick Ruffini suggests Rush Limbaugh, Ben Smith from Politico suggests Seth Lipsky, and, to bring it full circle, George Packer suggests Frum. I think Greg Pollowitz at NRO’s Media Blog is probably right, though, that it won’t be a conservative at all–Greg’s money is on Keith Olbermann.
