One of the first thing Obama did was make Dan Rooney Ambassador to Ireland. Now Ambassadors tend to be one of two types of people, professional diplomats who do all the work and Political supporters of the Sitting President as rewards for Domestic Political Support.

The local Democrats do NOT need their support, Pittsburgh is overwhelmingly Democratic (No Republican had sat on City Council since 1934, when the last one lost his seat, the last Republican Mayor term ended in 1930). The Suburbs have been more Friendly to the GOP, but Allegheny County Council had always had a Majority of Democrats elected. Now the first County Executive was elected in 2000
Side note on the 2000 Allegheny County Executive election. Prior to 2000, Allegheny County had a three man Commissioner set of Government, replaced by a County Executive and a County Council in 2000. In the first election for County Executive the Democratic Candidate that year was Cyril Wecht. Cyril Wecht was (and is) a brilliant person, a medical doctor, a medical examiner (Coroner. famous for his critique on the autopsy of John Kennedy) and a lawyer. The problem is Wecht had a habit of either people liking him or hating him, nothing in between. Worse, in 2000 the GOP decided to bring back up some old charges against Wecht implying Wecht had stolen money from the County when Wecht had been County Coroner. A federal jury had heard the evidence in the 1980s and found that, yes Wecht had used County Facilities to perform Autopsies Wecht did and was paid for as a private medical examiner, but it was facilities Wecht had paid for with proceeds from such autopsies. The Jury found no criminal liability for no intent was found by the jury of Wecht wanting to rip off the county. The problem for Wecht was it was enough for him to barely lose the election in 2000 after the GOP poured all types of money into the Campaign. In the next election for County Executive Dan Onorato easily defeated the GOP candidate (Seeking reelection).

Beside the death penalty another big difference is Gun Control, Philadelphia is much more into such gun control then even the City of Pittsburgh (Which is the hot bed of Liberalism in Western Pennsylvania), Once outside those Cities, support for Gun Control is much higher in the Suburbs of Philadelphia then in the Suburbs of Pittsburgh. The difference was best seen in the Democratic Primary election of 1980 between Jimmy Carter and Edward Kennedy. In polls taken at that time period, every sub-group of Democrats that support Edward Kennedy in the Eastern half of the State, Supported Jimmy Carter in the Western Half of the State. This difference has been known since the Colonial Period, reinforced during the Industrializing period of 1850-1930 and remains to this day.
Thus I can NOT see the Rooneys giving more money to the GOP then the Democratic Party except for some commercial reasons such as their investments in Racetracks in Florida and New York City Areas (Which I define as anything South of West Point New York).
