From the twilight zone department: various polls put Scott Brown, Republican challenger for the special election for Ted Kennedy's former Senate seat in Massachusetts, within striking distance of the Democratic favorite, Martha Coakley. Public Policy Polling yesterday released a poll suggesting a statistical dead heat in the race, while Rasmussen released poll results on January 4th showing Coakley with a 50% - 41% edge. The Boston Globe, however, counters with a poll showing likely voters leaning 53% to 36% towards Coakley - more in line with historical results in Massachusetts.
