For a few weeks now I have joined my fellow partisan Democrats, drinking when I was not crying.

The awful memories of those stunned TV commentators snatching defeat from the jaws of a great early exit poll victory. The hard-earned accomplishments of the past 8 years now at risk due to and an unfit, unwelcome new president. Looking ahead to the damage inevitably inflicted by a unified Republican government on the environment, the social safety net and global leadership.

Yet as a new year begins, I find myself past the 5th stage of grief and on to an unexpected new state of mind: optimism.

Because looking beyond the ashes of 2016 and the inevitable initial defeats of 2017, I see immense opportunities for my party and our capacity to lead our country.

It’s a great time to be a Democrat. There are several reasons why.

First and most important, Democrats remain the party of the future. We are the young, the diverse, the tolerant and the educated. Trump’s negative appeals to fear, intolerance and hatred sow the seeds of future Republican defeats and marginalization.

Just as California Governor Pete Wilson’s Proposition 187 consigned the California GOP to permanent minority status, so too will Trump embrace of white nationalism and the alt-right doom the national GOP in a diversifying nation.

Second, Democrats can return to the offensive. President Obama accomplished a great deal, but as with the last years of both Presidents Bill Clinton William (Bill) Jefferson ClintonEpstein podcast host says he affiliated with elites from 'both sides of the aisle' Ruth Bader Ginsburg lies in repose at Supreme Court Business groups start gaming out a Biden administration MORE and George W. Bush’s tenure, it gets harder and harder to imagine and demand reform when you’re busy defending your existing initiatives.

Likewise, Secretary Hillary Clinton Hillary Diane Rodham ClintonDemocratic groups using Bloomberg money to launch M in Spanish language ads in Florida The Hill's Campaign Report: Presidential polls tighten weeks out from Election Day More than 50 Latino faith leaders endorse Biden MORE is a phenomenal person, and was immensely qualified to be president, but candidates from the past bring baggage from the past. Now is the time to fight for the future.

In that regard, I am very excited by the rising generation of Democratic leaders.

Representing every state and fresh ideas, leaders such as New Jersey Senator Cory Booker, incoming California Attorney General Xavier Becerra Xavier BecerraState AGs condemn HUD rule allowing shelters to serve people on basis of biological sex OVERNIGHT ENERGY: Trump casts doubt on climate change science during briefing on wildfires | Biden attacks Trump's climate record amid Western wildfires, lays out his plan | 20 states sue EPA over methane emissions standards rollback 20 states sue EPA over methane emissions standards rollback MORE, South Bend Mayor Pete Buttigieg, Louisiana Congressman Cedric Richmond, and Illinois Senator Tammy Duckworth fill out a fantastic bench of creative, capable, inspiring national figures.

Leaders like these are ready to define the future of the Democratic Party, and I’m excited to help them do it.

Though many pundits see challenges for Democrats in 2018, I am optimistic there as well.

It is true we are defending 25 Senate seats around the nation and 10 in states won by Donald Trump, but presidents tend to struggle in midterm elections, especially when they are struggling to make good on their promises.

One does not need to be a partisan warrior to see how challenged President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

He promised that Mexico would pay for a border wall, that his secret plan to defeat ISIS would bring peace to the Middle East, that he would release his taxes, avoid conflicts of interest and end drug abuse and violent crime. Trump literally promised Americans would be “tired of winning” which seems regrettably unlikely.

Notwithstanding the partisan gerrymander, we will take back the House in 2018.

Democrats only need to pick up 23 seats to gain control.

Recall President Clinton lost 54 seats in his first midterm, while President Obama lost 63 in 2010. President Bush lost 31 in 2006 as Americans revolted against Congressional corruption and Executive incompetence. I’m expecting to hear “You’re doing a heck of a job, Secretary Perry” any day now. The Democrats will win in 2018 … and win bigly.

Five of the past 6 elections have been change elections.

The pendulum has swung back and forth between the parties because Americans desperately want change but have not been satisfied with the change they got. With new leaders and fresh ideas, Democrats stand ready to finally deliver the change Americans so badly want. But this will not happen by itself.

To the Democrats out there, 2016 is finally over. Time to stand up and dust yourselves off.

It may be just nearly January, but it will 2018 before you know it. Let’s not miss that future. It’s a great time to be a Democrat.

The opportunity is here. Let’s get to work.
