In Pennsylvania, more than a dozen third-party candidates have filed to appear on the November ballot for the presidential race, U.S. Senate, and statewide offices, raising concerns of a potential spoiler effect in close contests. Notable candidates include Robert F. Kennedy Jr. from the We the People Party, Jill Stein from the Green Party, and Claudia De la Cruz from the Party for Socialism and Liberation, while the Libertarian Party submitted signatures under a stand-in candidate. Kennedy's candidacy is particularly worrisome for major party strategists, as they believe he could outperform independent candidates in recent history. Legal challenges to the candidates' ballot access can be made until August 8, contingent on their meeting the 5,000 registered voter signature requirement. With 19 electoral votes at stake, Pennsylvania is a key battleground that has swung between parties in past elections. The Senate race is also competitive, featuring Democratic incumbent Bob Casey against Republican challenger David McCormick, alongside multiple third-party candidates.
