Democrats laser in on Pennsylvania as they scramble to keep Senate majority

Democrats' prospects in Montana and West Virginia look grim - and money is pouring in to help Trump-backed Dave McCormick

Pennsylvania has come into laser focus in the 2024 election as the must-win state of the presidential election. But further down the ballot is another race in the battleground state - one that could decide whether Democrats are able to hold on to a one-seat majority in the Senate.

With the party bracing to lose a seat in West Virginia and incumbent Jon Tester's prospects looking grim in Montana, a lot of attention and money is flowing into the Senate race between Democrat Bob Casey and Republican Dave McCormick in Pennsylvania.
