Another poll from Public Policy Polling (PPP) also released Saturday evening, however, showed Obama up 6 points on Romney in the Keystone state.
A new Allentown Morning Call/Muhlenberg College poll from Sunday also showed the president up, with Obama holding a 3-point advantage in Pennsylvania, 49-46.
But the state once thought to be safely in Obama’s corner has become increasingly competitive in the past week as the Romney campaign has poured resources there, capped off by Romney’s planned visit on Sunday.
Romney campaign officials say that the move into Pennsylvania is a sign that the campaign is expanding the map into once safe Democratic territory. Romney political director Rich Beeson told “Fox News Sunday” that the move is similar to Obama’s push in Indiana in the final days of the 2008 campaign.
The Obama campaign counters that Romney’s move into Pennsylvania is a sign of desperation, citing polls showing him trailing in Ohio, a crucial battleground state. No Republican has won the presidency without capturing the Buckeye state.
“The battleground states which had been focused on are not working out for them,” senior Obama campaign adviser David Axelrod said Sunday.
He called the Romney push in Pennsylvania a sign the GOP nominee's campaign was in "deep trouble."
