Undecided leads in newest U.S. Senate poll on Sestak-Toomey matchup in Pa.

A new poll indicates a Joe Sestak-Pat Toomey race for U.S. Senate in Pennsylvania would be a close one, but “undecided” has the lead.

The poll by Robert Morris University in suburban Pittsburgh shows Democrat Joe Sestak with just over 34 percent support, while 28 percent of those surveyed favor incumbent Republican Pat Toomey.  Undecided voters are in the majority at this point, said Phillip Harold, a RMU professor of political science Phillip.

“Sestak-Toomey, head to head, it’s 37 percent undecided,” he said of the 2016 race.If Toomey’s opponent next year were three-term Allentown Mayor Ed Pawlowski, the results would be different, Harold said. “Toomey beats Pawlowski,  33 percent to 30 percent.”Toomey’s favorable rating in the poll is hovering at about 40 percent, while about a quarter of those surveyed have an unfavorable view of the incumbent senator from Pennsylvania.The poll has a margin or error of plus or minus 4 and a half percent.

Sestak of Delaware County was elected to two terms in the U.S. House of Representatives. Declining to run for re-election in 2010, he instead ran for the Senate, facing incumbent Sen. Arlen Specter. He beat Specter in the primary, but lost to Toomey in the general election.
