HARRISBURG (AP) – The U.S. Senate race in PA between Democrat incumbent Sen. Bob Casey and Republican David McCormick is headed for a statewide recount, as counties continued Wednesday to sort through outstanding ballots and the campaigns jousted over which ones should count. A noon deadline passed Wednesday for Casey to waive his right to a statewide recount and PA Secretary of State Al Schmidt announced that preliminary results had triggered a legally required statewide recount. As of Wednesday, McCormick led by about 28,000 votes out of more than 6.9 million ballots counted — inside the 0.5% margin threshold to trigger an automatic statewide recount under PA law. Counties must begin the recount no later than Nov. 20 and must finish by noon on Nov. 26. The Associated Press called the race for McCormick last week, concluding that not enough ballots remained to be counted in areas Casey was winning for him to take the lead.
