Pollster Scott Rasmussen’s latest numbers on that special Senate election in Massachusetts: Democrat Martha Coakley 49%, Republican Scott Brown 47%, independent candidate Joe Kennedy (no relation to the Kennedys) 3%. Rasmussen points out that this is not precisely comparable with his survey last week, which showed Coakley ahead 50%-41%, since in that survey it offered the choice of “some other candidate” and in this one Kennedy (whose inclusion in debates Coakley insisted on) was named. Turnout matters: this most recent poll shows Brown 2% ahead among those absolutely certain to vote. Obviously all these results are within the statistical margin of error, which means that either candidate could win.
Presumably this poll was taken last night, overlapping with the only televised debate of the campaign. It looks like Brown is picking up support as he becomes better known, while Coakley continues to hover right around the magic 50% mark, as she has done in all recent polls.
