The 53-year-old McCord, a former venture capitalist, was elected in 2008 in his first campaign for public office and has maintained a low profile in his first term.
In 2010, McCord made statewide headlines when he and Auditor General Jack Wagner refused to approve a $1 billion borrowing package advocated by then-Gov. Ed Rendell. All three men are Democrats, but Rendell backed down and accepted $650 million.
McCord also is a formidable fundraiser who reporting $2 million on hand through mid-September, contrasted with Vaughan's $22,000. McCord aired a couple of statewide TV ads, while Vaughan relied on radio ads and billboards to get her message out
Vaughan, 50, who has been a Washington County commissioner since 1995, has criticized McCord for not doing enough to avert a looming state pension crisis and to reduce state debt, but offered no proposals for change. This was her first statewide campaign.
