Mitt Romney just got the best political news he's had from Massachusetts since he won the governorship in 2002.  Elizabeth Warren, the poster girl for biographical fabulists, will stay as the Democratic nominee for Senate, twisting in the wind as the implications of her adoption of an identity as a Native American for career advancement sink in.  She has become an  object of widespread mockery, doing herself no good with her use of "family lore" as her documentation, and unable to dig her way out of the hole she finds herself in.

Because there is a severe media taboo (extending even to Fox News Channel) against mention of Barack Obama's use of a Kenyan birth as a fraudulent marketing ploy to enhance the value of his planned book, Warren will do nicely as a proxy.  Her lily white skin, haughty manner, and implausible claim to victimhood prevent her from being off limits.  She will have a secondary impact on Obama by making it plain that a close ally of the president made up something about herself for career advantage. 

Even though unmentionable in legacy media plus Fox, a critical mass of the American public knows about the literary agency's peddling of his prospective book as written by an exotic fellow with an exotic name and exotic birth and upbringing.

Christine McConville of the Boston Herald:

state Democratic Party chairman John Walsh, citing a recent poll and insisting the flap has had no effect on Warren's standing as the party's front-runner...said no one is talking about replacing her. "It's not a sentiment that is out there at all."

"The Democratic Party is really stuck," countered University of New Hampshire political science professor Andrew Smith. "They essentially cleared the path for her as a candidate, and they can't get rid of her now. She could conceivably drop out, but I doubt that will be the case, and I doubt the party will try to push her aside."

Smith and some Democrats say the party can't switch front-runners now - it's probably too late for a big name that could attract big money to jump in and gather the 10,000 signatures needed by a June 5 deadline.

"They're in a tough spot, but there's not a lot they can do about it," Smith said.

Nor can Obama do much. Faked identity is on the table as a point of discussion and mirth.
