Republican hopeful Pat Toomey for the first time registers 50% support in his race against incumbent Democrat Arlen Specter in Pennsylvania’s contest for the U.S. Senate.

The latest Rasmussen Reports telephone survey of likely voters in the state shows Specter earning 40% of the vote, a level he’s held steady at since the first of the year. Four percent (4%) prefer some other candidate, and six percent (6%) are undecided.

Toomey this month also makes his strongest showing to date against Specter’s Democratic Primary challenger, Congressman Joe Sestak. Toomey picks up 47% support to Sestak’s 36%. Given this match-up, five percent (5%) like another candidate, and 12% are undecided.
