(CNN) -- Need more evidence that Pennsylvania won't be a cakewalk this time around for President Barack Obama?
Then here you go: A Franklin and Marshall College poll of likely Keystone State voters released Wednesday indicates Obama with a 49 percent-45 percent edge over Republican nominee Mitt Romney. The president's four point advantage is within the survey's sampling error and is down from a nine point lead he had last month.
The new Franklin and Marshall poll is the fifth non-partisan, live operator survey released this month in Pennsylvania to indicate a close contest for the state's 20 electoral votes.
The Franklin and Marshall poll indicates the president with a 56 percent-37 percent lead over Romney on handling foreign policy, a 54 percent-39percent lead on being better able to understand the concerns of ordinary Americans and a 51 percent-42 percent lead on handling the job of military chief. But according to the poll, Romney has a 47-42 percent advantage on fixing the economy.
