Imagine four more years of unchecked corruption and naked grift. Four more years of broadsides against our democracy, our free press, and the very concept of truth. Four more years of fawning deference to Vladimir Putin abroad — and to the NRA here at home.

That doesn’t have to be our fate. In 28 days, Iowans can say enough, and take the first step toward beating Donald Trump and restoring the soul of our nation.

Restoring our soul means creating policies that reflect our shared values. That means ensuring that health care is a right for all — not just the wealthy — by giving every American the choice to either stick with a private plan or choose an affordable, quality Medicare-like public option. It means revitalizing the basic middle class bargain for all Americans, so that no one has to leave their hometown — be it Manhattan or Mason City, L.A. or Elkader — to find opportunity. It means banning assault weapons and limiting magazine clips, so that every parent can look their kids in the eye and tell them, “You will be safe at school.” Most of all, it means treating every person with dignity.

know how seriously you take your responsibility as caucusgoers, and I believe you’ll choose a candidate who can build a broad, diverse coalition to unify this nation around our common values — someone who understands that our country is made strong by the ideals and dignity of our people.

We don’t have to give in to Donald Trump’s dark, petty, angry vision of America. We can choose to be the more perfect union we have always aspired to be. We can restore the defining American promise — that no matter where you start in life, there’s nothing you can’t achieve. And, in doing so, we can restore the soul of our nation. I hope you’ll join me in that fight today — and that you’ll caucus for me on Feb. 3.
