HARRISBURG - Pennsylvania voters also decided hotly contested Democratic primary races for U.S. Senate and state attorney general.

Democrats backed their party establishment's choice, Katie McGinty, for U.S. Senate to challenge Republican incumbent Pat Toomey in November. They rejected former congressman Joe Sestak, who six years ago nearly won the office.McGinty was endorsed by President Barack Obama and was aided by millions of dollars from the party and its allies. Sestak lost to Toomey by just 2 percentage points in 2010, but was spurned by a party establishment that views him as a maverick.With almost all precincts reporting, McGinty had 42 percent, compared with 33 percent for Sestak and 20 percent for Fetterman.Democratic Party leaders recruited McGinty, who had spent more than a decade as a state and national environmental policy official. The money they poured into her campaign bought a surge of TV advertising, which helped her erase a polling gap with Sestak. The fall contest could help determine control of the U.S. Senate.She beat back sustained criticism from her rivals that she had taken advantage of a revolving door and had been paid handsomely by energy companies she had once regulated.Democrats picked Montgomery County Commissioner Josh Shapiro in a three-way race for the attorney general nomination against two career county prosecutors, and Republicans nominated state Sen. John Rafferty, of Montgomery County, over a career prosecutor and police officer.The candidates will vie to succeed Democrat Kathleen Kane, who decided not to seek a second term while she faces trial over allegations she unlawfully leaked grand jury information. Kane, the first woman and first Democrat to be elected the state's attorney general, has denied the accusations.In congressional races, Democratic U.S. Rep. Chaka Fattah lost his bid for a 12th term in a four-way primary as he faces trial on federal racketeering and bribery charges in May. Fattah, of Philadelphia, has denied any wrongdoing. Longtime House Rep. Dwight Evans won in the heavily Democratic district.
