PHILADELPHIA (AP) -- Barack Obama and Hillary Rodham Clinton could bring out a record number of Pennsylvania voters for the state's Democratic primary.
If more than 2.3 million of the 4.2 million registered party members show up at the polls, it would set a modern record for the state's Democratic presidential primary. Voters were out early across the state, including at a church in Allentown, where a line snaked out the door.
The current record -- of just under 55 percent -- was set in 1980, when Massachusetts Senator Ted Kennedy narrowly defeated then-President Carter in Pennsylvania.
Democratic enrollment began to soar earlier this year when it became apparent that neither candidate would clinch the nomination before Pennsylvania's primary.
