Nationally, Catholic voters have been a crucial swing constituency in recent presidential elections, particularly in the state of Pennsylvania where they are expected to make up at least a quarter of the electorate. The state has seen a shift in voting patterns, with Donald Trump winning by a narrow margin in 2016 and Joe Biden securing a victory in 2020.
Biden's Catholic faith and connection with working-class Catholics were highlighted as factors that resonated with some voters. In the upcoming election, Trump is once again leading the Republican ticket, with a Catholic, JD Vance, as his running mate.
