Bonds will help Pennsylvania counties purchase new voting machines, Gov. Tom Wolf announced Tuesday.

Pennsylvania would fund up to $90 million to reimburse counties for 60 percent of the cost to upgrade their machines.

Counties must choose a new voting system that uses a paper trail by Dec. 31 and implement them by the 2020 election.

"They will make a decision we believe either in late July or early August, and then we'll begin the work of implementing a new system in time for the spring election in 2020," said Doug Smith, Erie County Clerk of Elections.

The Department of State has already begun giving out $14 million in mostly federal funding.
