The Morning Call: President Barack Obama, who political experts say will need a win in Pennsylvania to retain the White House, dipped to 35 percent approval among PA registered voters, according to a Muhlenberg College poll released Friday. Pennsylvania, with its million more registered Democratic voters than Republicans and its support for Democratic presidential candidates over the last two decades, is deemed by political experts a must-win for Obama. But if the election were held today, it doesn't appear that Obama would win it.
