HARRISBURG, Pa. - Pennsylvania counties ground through ballot counting Tuesday a week after voting concluded in a high-turnout election that tested a new vote-by-mail law and led some Republicans to doubt its results.Preliminary counts that were due at the close of business Tuesday from counties to the Department of State do not have to be complete but will be watched for how they might affect the presidential race numbers.They also may lead voters to ask officials to recount the tallies in their local precincts.Democratic candidate Joe Biden currently holds a 46,000-vote margin, too wide a gap for Republican President Donald Trump to qualify for a mandatory recount.No state or county election official has reported fraud or any other.
