Scott Rasmussen just told the Boston Fox affiliate that Democrat Martha Coakley has a relatively narrow lead of 50–41 percent over GOP state senator Scott Brown.

A Republican win in Massachusetts is still a longshot, but these numbers are in the range of the possible. The question is: Are these numbers close enough to get Martha Coakley to actually start campaigning? She’s been the invisible gal since winning the primary.

Will this margin energize Scott Brown’s supporters, or will it awake the sleeping Democratic giant in Massachusetts?
