HARRISBURG, Pa. (AP) — A court decision in the presidential battleground of Pennsylvania means voters can cast a provisional ballot in place of a mail-in ballot that is rejected for a garden-variety mistake they made when they returned it. Lawyers in the case say Thursday’s decision will apply to all counties. An appeal could be filed within days to the state Supreme Court. Parties in the case couldn’t immediately say how many Pennsylvania counties don’t let voters replace a rejected mail-in ballot with a provisional ballot. Democrats typically outvote Republicans by mail by about 3-to-1 in Pennsylvania, and the decision could mean that hundreds or thousands more votes are counted in November’s election.
