The current impeachment trial of former President Donald Trump is an ever-present reminder of the controversy surrounding last November’s election. Pennsylvania voters found themselves at the center of that controversy, with claims and counterclaims over the legitimacy of the voting process.

Add in the COVID-19 pandemic, which will still be a public health problem this spring, and it’s understandable if some Keystone State voters feel gun shy about the process. Many will likely choose to vote by mail or absentee, given the ongoing pandemic.

But whether it’s at the post office or your local polling station, here are a few things to keep in mind for the upcoming elections on May 18:

— You have to be registered by May 3 in any of the five Delaware Valley counties to vote in that primary. The general election is on November 2. Because Pennsylvania has closed primaries, voters who choose Democrat or Republican can only vote for candidates from their own party, or in non-partisan contests.

— If you are voting by mail, your ballot application needs to be received by the county by May 11. This means everyone who plans to vote by mail, even if you elected to do so going forward every year, needs to re-apply. “Any resident who wants to vote by mail will need to apply again this year, even if you voted by mail in 2020,” said Kenneth Lawrence, chair of the Montgomery County Board of Elections besides being a county commissioner.

— Double-check that the registration is correct. If you moved, switched parties, married or divorced (and changed your last name in the process), everything still works as it should when it comes time casting your ballot. As we know, Pennsylvania was on the receiving end of a few lawsuits regarding votes in 2020, and the clearer the process, the better.

“We encourage everyone to check their voter registration before May 3 to make sure their information is up to date,” advises Montgomery County Board of Commissioners Chair Dr. Valerie Arkoosh. “We know that residents may still want to vote by mail due to the COVID-19 pandemic,” she said. “Rest assured, whether you choose to vote by mail or in person, your vote will be counted.”
