As Illinois Republicans vote in the state's presidential primary, GOP hopeful Rick Santorum is reconnecting with a son of Illinois who's remembered for an afternoon spent in Pennsylvania.
Santorum plans to watch Tuesday's results from Illinois at a campaign party in Gettysburg, Pa., the venue for President Abraham Lincoln's famous Civil War address.
Santorum had campaigned in Illinois and looks to continue his trend of doing well in rural, conservative areas while largely ceding urban areas to Republican front-runner Mitt Romney.
Santorum aides cast his decision to return to Pennsylvania as a nod to Illinois' famous son. It's also a political move, too. Santorum represented Pennsylvania in the House and the Senate, and his aides have said he must do well there to continue a campaign that lags behind Romney's.
