A state which had previously been thought of as a lock and indeed a must-win for any Democrat seeking the Presidency, Pennsylvania is now tightening up in the remaining days. The latest polling data indicates a mere 4 point advantage for President Obama in a state he won handily in 2008 by 10 points.

Report from CBS Philly:

HARRISBURG, Pa (CBS) — A new Franklin and Marshall Poll shows that Republican Mitt Romney is now within striking distance of President Obama in Pennsylvania.

Less than a week before election day, the Franklin and Marshall College Poll shows Romney now trailing Obama by just four percentage points among likely Pennsylvania voters – 45-percent to 49-percent, compared to a nine point deficit in a September F&M survey. Poll director Terry Madonna says Romney is closing in, but he may be running out of time.

“Momentum is with Romney,” Madonna says. “Four percentage points is still a big hurdle. It is doable for Governor Romney, but very, very difficult.”

Madonna says for the first time all year in the F&M poll, Romney now leads Obama in the category of who can best fix the economy.

As stated in the article, time is now Romney’s enemy in this case since the President is hoping to run out the clock and put an end to any GOP insurgency in these typically Democratic strongholds.

The battleground is expanding in states like Ohio, Wisconsin, Michigan and Pennsylvania continue to tighten. On the other hand, President Obama still holds a lead on average in all of those states though the needle has been moving in Romney’s direction over the month of October.
