HARRISBURG, Pa. (AP) — Republican lawmakers aren’t committing to the money sought by Democratic Pennsylvania Gov. Tom Wolf to back up his demand that counties replace their voting machines by 2020. Republicans who control the Legislature say their budget counterproposal doesn’t include the $15 million Wolf requested. Republicans say that there’s no example of an election irregularity in Pennsylvania and that counties that already use machines with a paper-based backup shouldn’t be forced to buy new machines.
