He means Elizabeth Warren - Legal Insurrection: "Scott Brown surges ahead of Martha Coakley."  One poll was interesting but two polls may be a trend.

I don't know how the whole Cherokee issue is affecting perceptions of Warren but, as a citizen of the Commonwealth, she is running the most vacuous TV ads, full of eye-rolling platitudes like "Washington is sending billions to oil companies!"  Really?  Do they wire it or are we talking about suitcases stuffed with cash?  This past week, Warren's ham-handed attempt to tie Brown to the Akin controversy almost certainly turned away more voters.  This is a shrill and flailing campaign.
