FIRST: Nate Silver's FiveThirtyEight moved our race to a toss up. It's the closest race in the entire country.

THEN: Mitch McConnell and his allies added an additional $4.3 MILLION in attack ads in Iowa, bringing their total spend to more than $80 MILLION against Theresa.

NOW: McConnell's attacks are working. The most recent polls show us trailing Senator Ernst by one point. That's still within the margin of error, but we're losing ground. Fast.

This isn't good, John. McConnell knows Iowa will determine the future of his Senate majority. He will do -- and spend -- whatever it takes to defeat us and keep control.

We can't fight back against McConnell's attacks without your help. We're not taking any corporate PAC money, so it's up to this grassroots team to have Theresa's back. Control of the Senate hinges on Iowa and we're running out of time to fight back. Rush a donation of $5, or whatever you can, right away.

What we do now during the final stretch determines the outcome of this race. Flipping the Senate has never been more important and with Iowans already voting, we can't take our foot off the gas. But our fundraising has taken a dip over the past few days, just when it's most critical for us to ramp up our voter outreach. We can't afford to make any more budget cuts or talk to even fewer voters in this final stretch.

Flipping the Senate means flipping Iowa. If we lose here, Democrats lose their one shot at taking back the Senate majority. And if we want to win here in Iowa, we need to get our fundraising back on track immediately before we fall further behind in the polls.

John, we're counting on your support during the final stretch. Help us get back on track by pitching in $5, or whatever you can, right now. Together, we're going to flip this seat and take back the Senate.

Thank you,

Team Greenfield
