Challenges in electoral integrity include voter suppression, electoral fraud, and lack of transparency in electoral processes. Factors such as disenfranchisement and gerrymandering can skew representation, while unreliable voting technology poses risks for accurate vote counting. Additionally, external influences, like foreign interference, threaten the legitimacy of elections. Ensuring fair access, protecting against fraud, and fostering public trust are essential to uphold the integrity of democratic systems and maintain confidence in the electoral process.
