The answer is: We can do a lot — if we do it together. We can build an economy for tomorrow, not yesterday, where being middle class means something again. We can strengthen families and communities, because when families get ahead, our country gets ahead, too. We can fix our dysfunctional political system and get unaccountable money out of it once and for all, even if that takes a constitutional amendment. And we can protect our country from the threats that we see around the world and ones that are still over the horizon.

These are the four big fights I’m taking on for you, but I can’t do it alone. We’ve got to tackle this together. We need to build on the success, the hard work and the innovation I found in Iowa. As school principal Jason McLaughlin put it, Iowans are “pragmatic, proud people.” That’s certainly what I saw first-hand this month. And it’s that spirit that’s going to help move our country forward.
