Democratic U.S. Sen. Bob Casey and Republican David McCormick are set to be the sole candidates on the ballots for Pennsylvania's April primary following a ruling by the state's highest court. This decision comes after three relatively unknown candidates faced successful court challenges to their paperwork, paving the way for Casey and McCormick to secure uncontested victories in their respective party primary elections on April 23.
The upcoming November election between Casey and McCormick is anticipated to be one of the most closely watched and expensive races in the country. This year poses a challenging Senate map for Democrats, requiring them to defend incumbents in red and swing states.
