Who can catch Dan Onorato?

Three polls released Wednesday morning drive home the point that the Allegheny County executive remains the firm frontrunner for the Democratic gubernatorial nomination.

None of them showed Onorato winning by a margin of less than 22 percentage points, with one showing him by as many as 27 points.

A Quinnipiac University poll showed the front-runner garnering 38 percent of the vote, with Auditor General Jack Wagner the next closest at 11 percent. State Senator Anthony Williams pulls 10 percent, while Montgomery County Commissioner Joe Hoeffel stands at 9 percent, according to the poll.

The results are mirrored in a Franklin & Marshall College poll also released in the morning, albeit with a higher percentage of undecided voters. The poll showed Onorato drawing 27 percent support among likely Democratic voters,  with Wagner and Williams tied for second, each with just 5 percent of the vote. Hoeffel, again in last, drew 4 percent support, according to the survey.

The Muhlenberg College/Morning Call tracking poll has shown Onorato with a big edge for more than a week, and Wednesday’s results were no different. He has 37 percent of the vote, in the survey, up from 33 percent the day before.

The big difference in the tracking poll is the support shown for Williams, who drew 15 percent, 6 points more than third-place Wagner. The poll reported Hoeffel at 8 percent.
