Yes, Dom is mostly conservative. He is a very good talk show host. Been around a long time.
The local talk radio station, "The Big Talker" 1210AM, is a healthy blowtorch and is basically the only game in town for (non-sports) talk radio. So it is as effective as anything can be in the Philly area for "getting the word out" to moderates and liberals. The Philadelphia Inquirer (the only real newspaper in town) is a hopeless liberal mouthpiece for the DNC, but fortunately the New York Post is readily available at every Wawa and 7-11. The NY Post actually has a pretty good circulation in the area. It is the paper I pick up every day.
Dom was reluctant to touch this story early on. From what I've gathered tonight, local vets that he trusts put a word in for O,Neill.
I better qualify this: There is another newspaper in Philadelphia, The Daily News, but that paper is unabashedly targeted at the urban hip-hop audience, and its editorial content reflects exactly that. Nobody who is serious pays much attention to the paper's editorial hollering.
On the other hand, The Daily News has always had a solid sports section and, incredibly (considering its editorial bent), the paper usually shoots pretty straight in its reporting, even when the news is bad for the Democrats. The Daily News certainly plays it straighter than the Inquirer in this regard.
