Updated:HARRISBURG, Pa. (AP) (AP)ong> - 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.
Meanwhile, Romney could name his running mate by the end of the week, a top adviser said Monday.
The announcement, if it happens according to the adviser's timetable, would come several weeks before presidential candidates traditionally reveal their picks for the second slot on the ticket. It would also come as Romney's campaign seeks to deflect intensifying criticism from President Barack Obama, other Democrats and some Republicans over Romney's business record and refusal to release years of personal income tax filings.
Outside a Louisiana fundraiser on Monday, senior adviser Eric Fehrnstrom said Romney hadn't finalized his decision but that an announcement could come within days.
Asked specifically whether Romney could announce his vice presidential pick this week, Fehrnstrom said: "Technically it could, but the governor hasn't made a decision. It will only happen after he makes a decision."
Romney traveled to Louisiana to attend a private fundraiser alongside Louisiana Gov. Bobby Jindal, who is among those on Romney's short list for vice president. Romney raised an estimated $2 million at the event, where 40 donors paid $50,000 to attend.
Fehrnstrom said Romney and Jindal met privately earlier Monday but did not discuss the vice presidential selection process.
Jindal has been campaigning aggressively for Romney in recent weeks, as have others thought to be under consideration. They include Ohio Sen. Rob Portman, former Minnesota Gov. Tim Pawlenty, Wisconsin Rep. Paul Ryan and Florida Sen. Marco Rubio, among others.
"Maybe you've noticed, our president has run an increasingly desperate and negative campaign. It seems like every time you turn on the TV you hear another false and malicious attack," Jindal told Romney's donors. "This president cannot run on his record. He has to lie about Gov. Romney's record."
Romney did not address speculation about his running mate, but praised Jindal's work in Louisiana.
"What I have seen watching this governor in the short years he's been here has really opened my eyes and people across the country to see what one person can do," Romney said of Jindal.
Choosing a running mate is perhaps the most important decision Romney will make before the Nov. 6 general election, now less than four months away. In the 2008 presidential race, Sen. John McCain's selection of Alaska Gov. Sarah Palin helped define his losing bid.
Romney has emphasized experience as the most important attribute in a running mate. Careful and risk averse, he's expected to make a relatively safe pick that won't shake up the race or overshadow his candidacy.
