U.S. Sen. Scott Brown sure went for hero to zero in record time. Now, he’s a traitor and a RINO.

James Taranto tells conservatives to grow up.

If Scott Brown is a RINO, any conservative with an semblance of sanity should drop to his knees and say a prayer of thanks for the creation of RINOs. If the species didn’t exist, Sen. Martha Coakley would be the 60th vote in favor of ObamaCare. No, scratch that. She’d be the 62nd vote for ObamaCare, the 60th and 61st coming from the Maine Democrats who would have soundly defeated whatever “real” Republicans ran in place of Snowe and Collins.

Kathleen Parker hits the same theme.

But when the vote was tallied, 13 Republican senators became “traitors.” What was that Steve Martin line? “Cats and dogs … living together!”
