Both camps agreed to the cancellation, so this isn’t a partisan thing. The two have been neck and neck the entire campaign, with a Boston Globe poll today showing Brown leading Warren by a statistically-insignificant 2 points. source
» Hey, wha’ happen? Warren’s rise may be due in part to an “announcement boost;” she was long-rumored as a candidate, and her official entry in the race may have fired up a contingent of Democratic voters. Perhaps more significant of a factor, however, is Brown’s plummeting popularity. Back in December, he was the 16th most popular Senator in the country, out of 87 polled. Now, Brown is in 61st place, and his favorability has dropped by 25 points.
» Well, technically, she’s not in the race yet; she’s just formed an exploratory committee. But if Warren gets in, this will be a nice coup for Democrats, as she’s absolutely adored by progressives and could stand a shot at unseating Scott Brown. If “Downtown Scotty Brown” goes down, and Democrats gain a Senate seat they would have probably otherwise lost, Republicans will probably regret preemptively blocking Warren’s appointment to the CFPB.
