Top three takeaways from the final and often contentious Pennsylvania Senate debate

Sparks flew Tuesday when Sen. Bob Casey (D-PA) and Republican candidate Dave McCormick met on the debate stage for their second and final standoff ahead of the November election.

The two candidates were pressed on a number of issues, including the economy, abortion, immigration, and more — with both Casey and McCormick taking stabs at their opponent in what is shaping up to be one of the most competitive Senate races this year. The race is also one of the most expensive races of the 2024 cycle, with more than $190 million being spent on the contest so far.
