Specter-Sestak primary in Pennsylvania a dead heat

Pennsylvania’s Democratic Primary is a month away, and the race between incumbent Senator Arlen Specter and challenger Joe Sestak is now a dead heat.

A new Rasmussen Reports telephone survey of likely primary voters in the state finds Specter with 44% of the vote, his lowest level of support in 10 months of surveying. Sestak, a congressman from the Philadelphia suburbs, earns 42% support this month, a level he’s hit several times but never exceeded.

Four percent (4%) of likely Democratic primary voters prefer some other candidate in the race, and 10% are undecided.

A month ago, Specter had a 48% to 37% lead in the contest. But Specter has been losing ground since January.
