GOP's Brown Edging Coakley in Latest Massachusetts Senate Poll

But even though Brown's lead is within the margin of error, Suffolk's David Paleologos called the results "a massive change in the political landscape."

The Suffolk poll attributes Brown's showing to support from independents, among whom he leads Coakley by 65 percent to 30 percent. It also says Brown is being helped by opposition to the health care reform legislation working its way through Congress.

Brown draws 91 percent of the Republican vote, a minority in Massachusetts, but the poll shows him poaching 17 percent of Democrats.
