Chunky Reese Witherspoon adopts the conventional wisdom:
Some of DeMint’s admirers quickly portrayed this move as a brilliant way to expand his campaign to remake the Republican Party. But it’s more likely that moving from the Senate to the world of think tank fund-raising (where he’ll probably excel) and policy (where his experience is thinner) will reduce his public profile, and close a chapter in the history of conservatism in the process.
It seems few people have twigged to the fact that quitting the Senate and moving to Heritage enables DeMint to widen his contacts in movement conservatism, glad-hand the big money people, and, perhaps most importantly, avoid potentially politically-damaging votes in the Senate.
What I'm saying is DeMint is running for president. That this has been so rarely mentioned since the announcement somewhat stuns me.
