Latest from Nate Silver:

Polling expert Nate Silver rated Iowa’s Senate race the closest Senate race in the nation.

Let’s be clear: I know better than to treat a 0.9-point polling lead like destiny.

This race is coming down to the wire, and thousands of voters remain undecided.

I’ve been here before — I won my first election by just six votes. I learned from that experience that you never know which door, phone call, or casual conversation could tip the balance.

So instead of taking it easy, I’m following the advice of my political hero, former U.S. Senator Tom Harkin: campaign like you’re behind until the final ballot is counted.

And I’d love to end this email there, without bugging you for money.

But we’re an all-grassroots operation facing the full force of the MAGA money machine, so I hope you won’t click away just yet.

If supporters like you chip in just $0.9 to help me grow my 0.9-point lead, I’ll be able to put in the miles I need to win this race and flip the Senate majority. The stakes are too high, the consequences too great, to sit on the sidelines.
