Just more than a month before the Democratic gubernatorial primary, Pennsylvania voters still don't know who's running.
The latest Quinnipiac University poll surveys likely voters. That's a change from previous polls, which talked to registered voters.
Polling Director Peter Brown says this is a more accurate picture of who will show up to vote on May 18th.
Brown says Allegheny County Executive Dan Onorato leads with 20 percent,Montgomery County Commissioner Joe Hoeffel has 15%, Auditor General Jack Wagner 13% and State Senator Anthony Williams received 5%. but Brown says it's still a wide-open race.
"Half the voters don't know who they're for, and of those who are for somebody, 70 percent say they may change their mind. That's pretty much not plugged in. Again, primaries tend to have lower turnouts than general elections, and this is one that has not yet caught the public's imagination."
Brown says he expects voters to tune in over the next six weeks, when television ads start blanketing the airwaves.
Right now Onorato is the only candidate airing spots. Senator Anthony Williams will start advertising next week.
Among likely Republican voters in the gubernatorial primary, Attorney General Tom Corbett leads State Representative Sam Rohrer 58% to 7% with 35% undecided.
