In Pennsylvania, both Vice President Kamala Harris and former President Donald Trump are making final campaign appearances ahead of a crucial election, amidst rising concerns over election integrity. Last-minute challenges have been filed against thousands of mail-in ballots, particularly targeting overseas voters, raising alarms among voting rights groups and local election officials. These challenges, attributed to Republican state senators, have been described as 'bad-faith' actions that create unnecessary stress for election boards. Meanwhile, reports indicate that approximately 15,000 voters in Erie County did not receive their requested mail-in ballots, prompting local Democratic efforts to assist affected voters. Despite these challenges, Pennsylvania Secretary of the Commonwealth Al Schmidt remains confident that voters will be able to cast their ballots. As Election Day approaches, the situation underscores the heightened scrutiny and complexity surrounding the voting process in this battleground state.
