The "kept conservative"

Jerry Bowyer, in this piece at Forbes, does a good job in sizing up the Vichy conservatives.

The kept conservative’s announced job is to represent the conservative point of view, but their real job is to give the illusion of balance without really challenging any of the core tenets of liberalism. They spend lots of time ‘reinventing’ the Republican Party, and the new invention is always the same: more liberal. They live among liberals, their friends are liberals, and, of course, they are paid by liberals.
