The Pennsylvania U.S. Senate race between Democratic incumbent Bob Casey Jr. and Republican Dave McCormick is crucial for determining control of a closely divided Senate. Both candidates participated in two highly charged debates, where Casey criticized McCormick for his connections to China and his past as a hedge fund CEO, while McCormick labeled Casey a career politician aligned with President Biden. Key issues discussed included abortion rights, with Casey supporting Roe v. Wade and McCormick advocating for states' decision-making, as well as gun laws and clean energy policy. The outcome of this expensive and closely watched race in a pivotal swing state could significantly influence the Senate's balance of power. Mail-in voting has already commenced, with Casey seeking a fourth term and McCormick attempting a second Senate bid after narrowly losing in a previous GOP primary.
