VIDEO: The Scott Brown Effect in Massachusetts

Historically democratic Massachusetts made history earlier this year when Republican Scott Brown beat Democrat Martha Coakley in a special election for the late Senator Ted Kennedy's seat in Congress. That was the first election that started the 2010 momentum for the GOP.

As the primary season wraps up, Massachusetts Republicans are focused on District 10, the land from the South Shore to the tip of Cape Cod. This district is the most conservative in the Bay State (Scott Brown took more than 60 percent of the vote here) and considered winnable by the GOP. The seat is open, with Democratic Representative Bill Delahunt not seeking re-election. In the final days before the September 14th primary, national star power is showing up for the Republican contenders; Governor Mitt Romney for Jeff Perry and Rudy Giuliani for Joe Malone.
