If Markos Moulitsas had his way there’d be no Affordable Care Act, no Dodd-Frank, no economic stimulus package. That’s the price when purity tests are applied to Democrats.

In a remarkable post yesterday, Moulitsas, founder and publisher of the progressive community site DailyKos, celebrates the departure from the Senate of 10 moderate Democrats over the last decade, and makes clear his hope that Senators Mark Pryor (D-Ark.) and Mary Landrieu (D-La.) lose their tough reelection battles this year. He doesn’t name some other moderates in tight races, like Mark Begich (D-Alaska) and Kay Hagan (D-N.C.), but his logic suggests that he’d be only too happy to say goodbye to them as well.


Moulitsas cares passionately about progressive politics, and he is a very savvy political observer—he knows that we must have Democratic majorities in Congress to make real progress, and that to create those majorities we must have Democrats win in red states like Arkansas, Alaska, Louisiana and North Carolina. Surely he can see that such Democrats must be somewhat different than the full-throated progressives that he name-checks in his essay.

Chuck Schumer and Rahm Emanuel understood that fact. As the chairmen of the DSCC and DCCC respectively, they aggressively recruited moderate leaders in red states and districts in 2006, and those moderates made Nancy Pelosi speaker of the House and Harry Reid Senate majority leader.

The majorities those moderates helped create made possible the progress of Barack Obama’s first term. Without them, the president would have been unable to reverse our slide toward depression with the stimulus, extend stable and secure health care coverage to all with the ACA, reform the worst abuses of the financial services sector with Dodd-Frank, remove the scourge of Don’t Ask, Don’t Tell from the military or pass a sensible immigration reform bill through the Senate.

A charge implicit in the Moulitsas post is that moderate Democrats lack political courage—that they would do the right thing if only they were brave enough. This just doesn’t withstand scrutiny. We actually sat in meetings with Senate moderates during the darkest days of the ACA deliberations. They knew that voting for the bill could send them to the Valley of the Doomed, and for many it did or still could. They put their careers on the line and took that vote anyway—every single moderate named in the piece who was still in the Senate voted for the ACA. So did those unnamed, like Senators Begich and Hagan. That is political courage.

It was laudable, but hardly courageous, for a Democrat from a blue state to have voted for the ACA. The last time a Democratic Senate incumbent lost in New York was 1899, and in Massachusetts it was 1947. They don’t stare political death in the face on any vote, ever. The moderates do.

Moulitsas might have a stronger case if the moderates he abhors were replaced by more liberal members. But almost every instance saw the opposite result. Of the 10 former Democratic senators that Moulitsas identifies, seven were replaced by Republicans, one by Montanan John Walsh, who is in a fight for his political life this year, and another by Democrat Joe Donnelly of Indiana, who is unlikely to make the DailyKos Pantheon of Progressiveness. Just one, Joe Lieberman, of midnight-blue Connecticut, was succeeded by someone to his left. Meanwhile, the moderate Democrats in tough fights this cycle are running against Tea Party true believers.

Democrats across the spectrum agree on far more than we disagree—almost all supported President Obama’s key initiatives, including universal health care and fundamental immigration reform. Most support new gun safety laws, marriage for gay couples and a vigorous federal response to climate change. Yet for some, that’s not pure enough.

If we are to make progress in a divided Washington—and if we are to protect the Democratic Senate majority—we simply must embrace a big tent for the Democratic Party. Even in purple states, there are not enough self-identified liberals to elect Democrats without their winning significant pluralities or majorities of moderates. The idea that more liberal candidates could win in places like Arkansas, Indiana or Alaska is pure fantasy. And to write off those states would consign Democrats to long-term congressional minority status.

We have all witnessed the devastating effect that the politics of purity can have, as the Republicans grapple with the toxic impact of the Tea Party on their candidates, their congressional leadership and their governing philosophy. Let’s not become them.
