John Edwards is caught in an affair. He is now disgraced, somewhat pathetic, and basically unemployable.
Newt Gingrich is caught in an affair. This follows him serving his first wife with divorce papers when she was in the hospital with cancer. He is a bestselling author, conservative savant, multimillionaire, and potential Republican presidential candidate.
UPDATE: A reader points to “Diaper Dave” Vitter, heavily favored to win re-election in Louisiana. So much for the theory advanced by some that it’s because Gingrich’s infidelities were so long ago, or because Edwards ran on more of a “pro-family” ideology (which actually he didn’t). No — it must be something else. Well, Edwards’ infidelity produced a child. Yes, that must be it! As Republicans repeatedly say (especially to conservative Catholics), infidelity is okay if you get your birth control right.
