Here is their article that they are referencing - Democrats get aggressive on remapping congressional lines
When it comes to sites like Politico, the OP article and the above-linked one, are MAJOR concessions to their usual spin and wording compared to stuff they have published in the past.
The issue over the past decade is that Democrats - like here in PA - spent a lot of resources UN-GERRYMANDERING prior GOP bullshit line-drawing - notably after the 2010 census and election.  Democrats LOST 62 seats in the House and 6 seats in the Senate, after literally running away from Obama and "Obamacare" (the ACA).  I saw it here on DU too.
It's ironic now that people are desperately depending on what Democrats ran away from 15 years ago.
But over that time, the GOP had seized states and gerrymandred themselves into a House majority for those 8 years following that 2010 election until we were able to "fix" SOME of what they broke (like here in PA, going from 13(R) - 5 (D) to 9 (R) - 9 (D)), and try to put guardrails in to make "fair maps". 
However since elections ARE the responsibility of STATES, and the SCOTUS has pretty much upheld gerrymandering, then you are seeing the backlash of the desperate GOP trying to regain and maintain what they had done 15 years ago.  And this means that Democrats are forced to work around their own guardrails to match that effort.
If anything, the biggest need is LOCAL (i.e., state/county/municipal - including governorships, state courts, as well as the state's elected legislative branch) and Democrats entrenching themselves in states in order to "control the lines".
Do we need to establish a more direct approach (other than suing them in court) to this admins lack of morality and staunch criminality?
What "direct approach" are you talking about other than the courts?  I would assume civil war?
