HARRISBURG, Pa. (AP) -- Republican presidential contender Mitt Romney is returning to Pennsylvania in hopes of putting the state in the GOP's win column for the first time since 1988.
Romney will speak Tuesday afternoon at the Pittsburgh-area offices of a gas drilling-services company. Democrats are countering with appearances in eastern Pennsylvania by Democratic National Committee Chair Debbie Wasserman Schultz.
She'll be at the United Auto Workers hall in Allentown and an Obama for America campaign office in Wilkes-Barre.
Romney's trip is at least his sixth to Pennsylvania in the last three months as he works to defeat President Barack Obama in what is viewed as one of the nation's most crucial swing states.
Pennsylvania has 20 electoral votes, tied for fifth-most. Obama beat Republican John McCain by 10 percentage points in 2008.
