ELITISM…. In general, the notion that a Democrat that few Americans have ever heard of is prepared to support John McCain is pretty inconsequential. There are some high-profile Republicans, including Iowa’s Jim Leach, backing Barack Obama, so the notion of a low-profile Democrat breaking party ranks seems largely forgettable.

But a lot of news outlets seem to be taking this pretty seriously, so it’s probably worth taking a closer look.

Lynn Forester de Rothschild, a prominent Hillary Clinton supporter and member of the Democratic National Committee’s Platform Committee, will endorse John McCain for president on Wednesday, her spokesman tells CNN.

The announcement will take place at a news conference on Capitol Hill, just blocks away from the DNC headquarters. Forester will “campaign and help him through the election,” the spokesman said of her plans to help the Republican presidential nominee.

Explaining her distaste for Obama, Forester said, “I feel like he is an elitist.”

Let me get this straight. Lynn Forester de Rothschild, who tends to go by “Lady Lynn Forester de Rothschild,” is the CEO of an international holding company. She’s married to Sir Evelyn de Rothschild, a British financier and a member of the prominent Rothschild banking family of England. She splits her time living in London and New York.

And she’s backing John McCain, a multimillionaire who has lost track of how many homes he owns, because she perceives Obama as “an elitist.”

I think D-Day had the right response: “Pardon me while I laugh hysterically for the next 10 minutes.”
