The Pennsylvania secretary of state said today that nearly 100,000 people have used the state’s online registration site since it launched in late August. The Department of State says more than 97,800 Pennsylvanians have used the technology, about 60 percent of them eligible citizens registering for the first time and 40 percent of them voters making updates to their registration, such as changing their name, address or party affiliation. March 28 is the deadline for residents to register or update their voter information before the April 26 primary election. The website for online registration is register.votesPA.com.
