Tonight, Bob Casey’s opponent, David McCormick, will take the stage at the Republican National Convention.

This is one of the largest Republican fundraising events of the cycle, and McCormick will have national attention like he’s never had before. Once he steps off stage, GOP donors and outside interest groups will start to flood Pennsylvania with donations to unseat Bob.

If we’re going to keep PA and the Senate blue, we have to be ready. So we’re asking: Will you make a donation of any amount before McCormick takes the stage?

Please use the links in this email to start a monthly donation through ActBlue.

We can’t do this without you, so thank you in advance.
