I’m not sure Sen. Obama’s current take on his “lipstick on a pig” comment helps much. From looking at the tape, he does seem clueless as to why the crowd is laughing and cheering. He’s sober and they’re happy and whooping it up.
That’s the real problem for Obama. The crowd clearly got the reference. Lipstick on a pig may normally get a few chuckles, but it’s so old that it doesn’t draw a cheering laugh without some sort of extra context.
The trouble for Sen. Obama is that he either has to say that he knew how the line would be taken or to say that he’s the kind of guy who is the last in the room to get a joke. Neither is an attractive option–especially for someone running for president.
