I'll give you the bad news first, friend: In an exclusive interview with CNN, Mitch McConnell said he's investing heavily to take back Senate control – and he named me one of his top targets for defeat. Experts now say I'm one of the most vulnerable senators up for reelection.

Here's the good news: We've overcome millions in GOP spending before, and we can do it again. But only if we hit our grassroots fundraising goals.

This is where you come in: At this critical moment, we're falling short of our big end-of-month goal, and time is running out before the deadline. I need folks like you to rush your support before it's too late.

That's why I'm asking directly: Will you please chip in $5 or more now – as much as you can spare by midnight – so we can reach our goal, be ready for whatever McConnell throws our way, and win?

Thanks for coming through at important moments like this.
