BREAKING: Nevadans begin voting in what experts rank "the most important Senate race in the country"

Friend – with Senate control hinging on my race in Nevada, and CNN calling me the most vulnerable senator in America, I need to ask you for a donation of $5. I hope you'll give me 60 seconds to explain why!

If you don't need 60 seconds, then please chip in a TRIPLE-MATCHED donation now to protect this seat and keep the Senate blue before our last end-of-month deadline.

Election forecasters from CNN to The New York Times are calling me the most vulnerable senator, and Nate Silver's FiveThirtyEight recently increased my chances of losing. Pundits across the board agree: The fate of our Senate majority comes down to Nevada – and right now, Nevadans are beginning to vote early.

It's why Mitch McConnell and his allies are pulling out all the stops in this race: $55 million worth of vicious attack ads flooding Nevada’s airwaves; MAGA rallies with Donald Trump and Ted Cruz; McConnell’s super PAC rerouting millions from Arizona into Nevada – they're going the whole nine yards.

Friend, there is no question about it: I am the GOP's #1 target – Nevada is the one seat they are determined to flip to take back Senate control. With polls showing me in a statistical tie with my Trump-endorsed opponent, I simply cannot fight back and pull ahead without your grassroots support. So if you've been waiting for the right moment to make your first donation of $5, it's right now.

The clock is ticking. So please, as voters begin casting ballots in the most important Senate race in the country, will you rush $5 (becomes $15) right now to make a race-defining difference, keep Nevada blue and defend our Democratic Senate majority?

At this point in the race, every grassroots dollar truly matters. I hope I can count on you.

¡La lucha sigue! The fight continues!
