Democratic U.S. Sen. Bob Casey of Pennsylvania has won re-election to a second term.
Casey capitalized on high name recognition and strong Democratic voter turnout Tuesday to counter a huge spending advantage by Republican businessman Tom Smith, a tea party favorite.
Casey is a former state treasurer and auditor general, and son of the late former governor, Robert P. Casey. He handily beat Republican Rick Santorum in 2006 for a second term.
Casey was an early supporter of President Barack Obama and voted for Obama's signature policies, including his health care law and stimulus bill. Smith had been heavily critical of those votes and had pledged to vote to repeal the health care law.
Casey said he has a lot of work to do, including trying to bridge partisan divides in Congress on economic and other issues.
Speaking to a boisterous crowd of supporters in Scranton, Casey said he would return to Washington to help middle-class families,
In his concession speech at a Pittsburgh hotel, Smith called for Republicans and Democrats to work together. Smith invested more than $16 million of his own money in the race, hammering Casey for months in TV and radio ads and forcing Casey to mount a strong response in the campaign's final weeks.
