Very clear Democrats will make voter suppression arguments a key theme of 2020. From Stacey Abrams response to the SOTU:

Let’s be clear. Voter suppression is real. From making it harder to register and stay on the rolls to moving and closing polling places, to rejecting lawful ballots, we can no longer ignore these threats to democracy. While I acknowledge the results of the 2018 election here in Georgia, I did not and we cannot accept efforts to undermine our right to vote. That’s why I started a nonpartisan organization called Fair Fight, to advocate for voting rights. This is the next battle for our democracy, one where all eligible citizens can have a say the vision they want for our country. We must reject the cynicism that says every vote cast to be counted is a power grab. Americans understand that these are the values our brave men and women in uniform and our veterans risk their lives to defend. The foundation of our moral leadership around the globe is free and fair elections, where voters pick their leaders, not where politicians pick their voters.
