No surprise really because trying to knock your primary opponents is part of the game. I expected the Corey O'Brien camp to challenge Brian Kelly's signatures.
Paige responded to the challenge in the pa2010 comments:
Since I haven’t been served with either complaint, I can’t comment beyond the obvious: this is a deplorable cowardly move that flatly contradicts Mr. Barletta’s frequent comments to the media that he welcomed additional challengers into the race. Assuming this report is correct, we are pleased that discovery will allow us to investigate Mr. Barletta’s own activities.
McGruff admits that the Barletta campaign has information that provide the basis for the challenge.
