The past two years have been filled with challenges, but 2019 holds the promise to be different. Our party is starting the new Congress with an additional measure of power and a renewed sense of purpose.

And that's a reason for hope.

In the year ahead, we have an opportunity to advance the fight for a better future for our children, an economy that works for everyone, a system that truly allows liberty and justice for all, and a healthy environment.

We will safeguard the economic and health security provided by the Affordable Care Act, Medicare, Medicaid, and Social Security. Any efforts to dismantle these programs will be met with fierce opposition.

And together, we can offer a forceful, coordinated response to the violent, hateful actions and rhetoric that have too often wormed their way into our current national conversation.

These new opportunities are a result of the work we have done together. So as I step down as the chair of the Democratic Senatorial Campaign Committee, I want to take one more moment to express my gratitude for all you've done.

For the past two years, I've traveled the country, talked with voters, and strategized with candidates. It's been challenging -- but every minute spent, every mile traveled, has lifted my spirits.

Because everywhere I've been, I've seen evidence of your commitment to fight for our values and our democracy.

In fact, that truth is evident right now in the halls of the Senate, where a new class of Democratic policymakers has already begun to demonstrate genuine leadership. Their ranks include Doug Jones, Jacky Rosen, and Kyrsten Sinema, who each won a Senate seat previously held by Republicans -- and I know that none of their victories would have been possible without you.

So, as I leave this role, and pass the leadership of this organization over to my friend and colleague, Senator Catherine Cortez Masto, my last ask of you is this: Keep the faith. Trust in our collective power to do good. And step forward into the new year confident in our ability to once again move our country forward along the path of building a more perfect union with more shared prosperity.
