“What is that black spot on Romney’s pin? It’s driving me crazy!”

Call us shallow, but we seem to spend waay too much time checking out politicians’ lapels. Not since Madeleine Albright have chest pins been such a big deal — why, now it’s almost politically incorrect for any candidate to show up with a naked suit, as Obama found out in 2007, when the presidential candidate was called out by a reporter for not sporting the flag.

“My attitude is that I’m less concerned about what you’re wearing on your lapel than what’s in your heart,” he told a campaign crowd in Iowa. But the pin came back — and stayed.

Today, a simple American flag is just the beginning. The new trend is to customize: Romney has worn the Secret Service lapel pin (Paul Ryan wears what appears to be a variant) and occasionally a flag with a GOP elephant. During the Republican debates, Newt Gingrich wore a pin of the flag that George Washington used in the Revolutionary War. So far, the president and Joe Biden are sticking to the classic American flag pin.

Not everyone liked Romney’s flag pin: Esquire’s Kurt Soller had no problem with the Secret Service logo, but thought it was too big: “Wearing a larger pin — which, in itself, is a piece of jewelry, though probably a pretty cheap one — just served, for me at least, to underline the wealth that’s come from all his business success. It’s a weird show of machismo.”

Hey, everybody’s a critic.
