Rick Santorum appeared to be the Republican presidential candidate to beat in Pennsylvania a month ago.
With the state primary four weeks away, Santorum now finds himself nearly tied with former Massachusetts Gov. Mitt Romney among the state's Republicans, and support is eroding rapidly, according to a Franklin & Marshall College poll out today.
"The real Rick Santorum has emerged," said G. Terry Madonna, director of the Franklin & Marshall College Poll.
"Santorum ran a disciplined campaign for eight months, but a month ago he began veering off message into all these cultural and social issues," Madonna said, referring to flare-ups over women in combat and contraceptives. "That may help with his core voters, but they're already with him. This is supposed to be about expanding your base."
