Compare the hysterical reactions to that dope Atkins in Missouri to the reactions to Warren. The republicans officially disowned Adkins, pretty much everyone called on him to drop out of the race, etc and all for an offhand comment .
Warren lied about being an Indian, clearly to benefit herself through affirmative action. You'd think democrats of all people would be livid about that, but the possibility of a Senate seat trumps decency, just like it did with Clinton. Now she is at least coloring very close to the lines on an issue important to lawyers, who pretty much are the heart of the democrat party.
