Friend – sorry to add another email to your inbox, but this can't wait: With just hours left until our crucial mid-month deadline, Catherine Cortez Masto let me know that she's still falling short of her $50,000 goal. That's why I'm asking you personally:

Because Catherine is Mitch McConnell's TOP target for defeat, his allies have already spent over a staggering $4 million to blanket the airwaves with attack ads against her. And it's clear their efforts are working:

Experts at the National Journal are now calling Catherine the MOST vulnerable senator on the ballot – and both CNN and Nate Silver's FiveThirtyEight announced that she's in severe danger of losing.

With a 50-50 split Senate, Democrats have ZERO room for error. To fight back against the national Republicans and GOP outside groups that are spending whatever it takes to flip Nevada red, Catherine needs an immediate surge in grassroots support. But time is running out, and not enough folks have stepped up to help defend this must-win seat.

That's why I'm calling on you to rush a donation right now. We can stop Mitch McConnell and the GOP from flipping this seat and the Senate – but ONLY if you step in during critical moments like this one. Please, will you rush $5 or more right now – as much as you can spare by midnight tonight – to keep Nevada and the Senate blue?

Thank you,

Jacky Rosen
