At first read of the title, I thought this was about “there’s no right or left” meaning you could substitute Republican for right and Democrat for left. Ultimately, the authors talking about tangentially and in line with your quote and OP:

“The only way to overcome the oligarchy and Trump’s divide-and-conquer strategy is for the rest of us to join together and win America back.

That means creating a multi-racial, multi-ethnic coalition of working-class, poor and middle-class Americans who will fight for democracy and oppose oligarchy.

White, black and Latino; union and non-union; evangelical and secular; immigrant and native-born – all focused on ending big money in politics, stopping corporate welfare and crony capitalism, busting up monopolies and stopping voter suppression.”

Edit-the point is to see beyond that possible connection and to what really needs to happen: the voters demanding and reinforcing their political powers. Practically, I think this asks people to not become jaded, “tune out”, and accept what’s going on as too big and beyond your influence.

Engage-read the news, do all the research you can muster on what politicians are doing, and come up with your own opinion. Then do your civic duties to reinforce your opinions.
