Primary election day is tomorrow and voters will be heading out to the polls to determine several county commissioner and district justice races. But the way people vote in Pennsylvania could be changing in the near future.

As it stands right now, when voters head to the polls in PA, they only have to show identification the first time they vote in their precinct. For each visit after, a person only has to sign the ledger. But some proposed legislation would change that, requiring voters to show ID each time they vote.

The broadest proposal won approval in the House State Government Committee last week. The law would require voters to show a proof of identification each time they head to the polls. Proponents hope requiring ID would cut down on voter fraud.

Representative Daryl Metcalfe, (R) Butler County, is proposing one of the voter ID pieces of legislation. He also wants to see the forms of eligible identification be limited to driver's license, passports, or state ID cards. He says the legislation just makes sense.

"All of the bills are good government type of bills creating more accountability, something that is sorely missed and needed here in Harrisburg. We are very hopeful this year that we can push it through the Senate and have Governor Corbett sign these good government measures," Metcalfe said during an interview in March.

Opponents of the bill say that this measure could disenfranchise voters who don't have ID, many who are elderly, African American or the working poor. They also say there is little evidence of voter fraud in Pennsylvania so the bill is wasteful.

At this point, there is no timetable for a full vote in the House.

As for tomorrow's primary, PA is a closed primary state. That means a voter has to be a registered Republican or Democrat to vote in tomorrow's races.
