I needed to share this update with you directly, friend: A self-funding GOP millionaire – one of Donald Trump's yes-men – just announced he's running against me for Ohio's Senate seat.

With national Republicans prepared to spend millions on this race, I need your immediate grassroots support to fight back ASAP. So I'm personally asking: Will you chip in right now and split $5 or more between me and Sen. Jeanne Shaheen so we can win and keep the Senate blue?

Here's why this is so important: with experts saying that Ohio could decide Senate control, Washington Republicans are doing everything in their power to defeat me and flip the Senate red. The truth is, I'm not scared. But I do know that where Trump goes, GOP dark money follows. That's why I'm personally reaching out to ask for your help.

This is, without a doubt, the biggest moment yet for our campaign – and how we respond in the next 24 hours is critically important to our chances of defending this seat.

Unlike my potential opponent, I don’t have a massive personal fortune to pour into this race. Instead, I'm relying on critical support from folks like you, one grassroots donation at a time. So please, will you split $5 or more now between me and Sen. Jeanne Shaheen to help us hit our $50,000 rapid-response goal, win in Ohio and keep the Senate blue?

Thank you for rushing your support to show the strength of this grassroots movement. With you by my side, I know that we'll be able to take on whatever the GOP throws our way – and win.
