It includes pages on the murky details surrounding the Cherokee heritage Warren has claimed, and the widely circulated video of a speech Warren gave last year that is considered to be the inspiration for Obama's "you didn't build that" comments that have provided conservatives with ample cannon fodder.
Warren's Wednesday-night speech could do more to boost her profile nationwide, as one of the party's up-and-comers, than it will to help her in her own race at home. Though Massachusetts remains staunchly blue, most recent polls show her locked in a tie with Brown, largely due to how well-liked he is in the state, and his efforts to come across as a moderate.
But Massachusetts Democratic Party spokesman Matt House called the site an attempt to "distract" voters, and merely another incident of what he characterized as Brown "throwing mud."
“Scott Brown has been throwing mud for weeks and this website is just the latest truckfull. That he launched this attack site while complaining about negative attacks is ridiculous. Brown has been attacking Elizabeth for months to distract from his own record voting against the interests of families in Massachusetts," he said.
Mud-slinging seems to be a common refrain from both sides of the race -- the Women for Brown group, affiliated with the Brown campaign, sent Warren a basket filled with laundry supplies to help her "clean up her act."
"With all the mudslinging Elizabeth Warren and her allies have been doing, we thought these laundry supplies would be a useful gift," said Angela Davis, chairwoman of the Women for Brown coalition. "We might never see Professor Warren fold her own clothes, but she does need to clean up her act and stop with her dirty politics."
