HARRISBURG, Pa. (AP) - Today is the deadline for Pennsylvanians to register to vote in the Nov. 4 election.

Republican Gov. Tom Corbett is battling for a second term against Democratic challenger Tom Wolf, who's led in the polls for months. Voters also will decide races for Congress and the Legislature.

People who want to register for the first time or to change their address or political party need to complete applications that must be postmarked or delivered to the applicant's county board of elections by the close of business Monday.

Applications can be downloaded from the Pennsylvania State Department's website or obtained at places that include county voter registration offices, the state departments of Public Welfare and Health, PennDOT photo and license centers, armed forces recruitment centers and area agencies on aging.
