The GOP primary field in Pennsylvania to challenge Democratic Sen. Bob Casey remains wide open, with the hopes of top party officials hanging on the potential entry of a high-profile candidate in a top-tier battleground state contest that could help define the Republican Party's path forward in 2024.
Former hedge fund CEO David McCormick is the favorite of party leaders and has drawn pledges of financial support from top Republican officials — should he decide to run. Meanwhile, state Sen. Doug Mastriano, a hard-right lawmaker who was endorsed by former President Donald Trump in last year’s race for governor but lost in a landslide, has said he will announce Thursday night whether he will run for Senate.
