SCOTT SIMON, HOST:
This is WEEKEND EDITION from NPR News. I'm Scott Simon. You could say that U.S. politics has entered a populous stage. The populous backlash against big government and big institutions has found expression on the right with the Tea Party but they have an expression on the left too in the movement of liberal economic populism.
The tensions between the Tea Party and the Republican establishment have been in full display for some time now. This week, we saw similar tensions getting stirred up among Democrats. NPR's national political correspondent, Mara Liasson explains.
MARA LIASSON, BYLINE: It started with an op-ed in the Wall Street Journal by the leaders of a centrist Democratic think tank called Third Way. Jim Kessler, one of the co-authors, called economic populism a dead end for Democrats.
JIM KESSLER: We wrote this because there needs to be a serious discussion, and this seems to be the right time to have it about what we're going to be doing with entitlements and investments in this country. There's a belief, I think, on one end of the party, not with everybody but with some, that we can have it all, we can expand entitlements and we can have investments, and our view is that's just not realistic.
LIASSON: Kessler's op-ed also took aim at populism as a political strategy, warning Democrats not to follow Massachusetts Senator Elizabeth Warren over the populist cliff. Warren is a hero to the liberal wing of the party who see her as the scourge of Wall Street and the op-ed got a furious response from Warren and her supporters, including Adam Green of the Progressive Change Campaign Committee.
ADAM GREEN: Third Way is a corporate funded think tank. In contract, Elizabeth Warren wing of the Democratic Party speaks to the overwhelming majority of Americans that really want an economy that looks out for the little guy and for them to take on both Social Security and Elizabeth Warren in their piece was pretty outrageous.
LIASSON: Like all intraparty feuds, this one can seem a little exaggerated. After all, both Third Way and the progressive group support the Dodd-Frank Wall Street regulation bill, and they both support raising taxes on the wealthy. On Social Security, both want to raise the amount of income subject to payroll taxes, although Warren and her allies would raise it more.
But the center and the left do part ways on the new push by progressives to expand Social Security benefits. Here's Elizabeth Warren on the Senate floor.
SENATOR ELIZABETH WARREN: Seniors have worked their entire lives and have paid into this system but right now more people than ever are on the edge of financial disaster once they retire and the numbers continue to get worse. That is why we should be talking about expanding Social Security benefits, not cutting them.
LIASSON: The new populist energy in the Democratic Party is fueled by growing frustration over income inequality, a shrinking middle class and the sense that Wall Street has escaped responsibility for the financial crisis.
JOE TRIPPI: Actually it's been an old fight that's been going on in the Democratic Party for a long, long time.
LIASSON: That's Democratic strategist and Fox News contributor, Joe Trippi. Back in 2004, Trippi ran the populist insurgent campaign of Howard Dean for president. Trippi says what's happening now is the beginning of an intraparty battle that will go on for the next three years as Democrats prepare for 2016. The battle will be fought along the ideological fault line that divides centrist Democrats from progressives.
TRIPPI: Obama's masked that. His success in winning two elections in a row has kind of masked that division in the Democratic Party, kind of pushed it under a little bit, particularly now as 2016 nears and there isn't somebody to bridge that gap, meaning a sitting president won't be standing in 2016. You're going to start to see that division come out in the open a little bit.
LIASSON: A successful Democratic presidential candidate has to rise on both wings, just like Barack Obama did and Bill Clinton before him. But Adam Green says that any candidate will be vetted by the progressive grassroots.
GREEN: At the end of the day, whoever the Democratic nominee is will have to answer key questions like are you going to cut Social Security benefits or are you going to embrace this new consensus position that's growing for Social Security benefit expansion? Will you hold Wall Street more accountable and reform it more, or will you be in their pocket?
Every Democrat will have to answer those questions, including Hilary Clinton. And if she answers wrong on these questions, there will be a lot of political space left for some insurgent Democrat to run and potentially pull another Obama.
LIASSON: Some insurgent Democrat, but Elizabeth Warren says it won't be her. Warren says she plans to serve out her full term in the Senate just as Barack Obama promised before he changed his mind. Mara Liasson, NPR News, Washington.
