This is huge, John. According to CNN, only four races in the whole country are a toss up, and Iowa is one of them.

Control of the Senate majority hinges on Iowa, John. Democrats need to flip four seats to take back the Senate majority and CNN's rating makes it clear: if we want to flip the Senate, we have to win here.

Attacks and dark money from national Republicans are flowing into the state: McConnell and his allies already plan to spend more than $60 MILLION on our race. Unlike her opponent, Theresa isn't taking a dime from corporate PACs. Instead, we're relying on grassroots donors like you to step up right now to help us flip this seat and the Senate.

Our race couldn't be closer -- recent polls show Theresa locked in a neck-and-neck race against Senator Ernst. Now CNN joins everyone from Politico to Cook Political Report in rating Iowa one of Democrats' top flip opportunities nationwide.

With the fate of the Senate majority on the line, we can't afford to lose. We've put together an aggressive plan to contact voters and counter McConnell's spending, but we can't put our plan in action without your grassroots support.

Pitch in $5, or whatever you can, right away to help us flip this seat and take back the Senate majority.
