Voters in parts of Southwest Philadelphia and Delaware County will go to the polls tomorrow for a special election to fill the 185th District House seat left vacant by the November death of Rep. Robert C. Donatucci.

Donatucci's wife, Maria Donatucci, a Democrat, faces Republican Lewis Harris in the race.

The Committee of Seventy will deploy volunteers to polling places in the district to answer voters' questions and resolve problems.

Voters may report problems through an election-protection hot line: 215-557-3600. Voters can locate their polling places online at guide.seventy.org or by calling 866-268-8603.
