LANCASTER, Pa. -

A new poll released Wednesday still has Democratic candidate Tom Wolf ahead in the race for Pennsylvania governor.

With his 47 percent, Wolf holds a 22 percentage point lead over Governor Tom Corbett in the Franklin and Marshall College poll, conducted in June.

Twenty-seven percent of those polled were still undecided.

Education and jobs are the issues voters say are most important to them in considering who to support for governor.

About one in four (26 percent) voters believes Corbett has performed sufficiently well to deserve re-election.
