One of Congress' most well-known liberals is leading the charge against a must-pass spending bill, calling it a giveaway to wealthy campaign donors and Wall Street banks.
Sen. Elizabeth Warren (D-Mass.) on Wednesday slammed the legislation, which would loosen derivatives-trading rules set in a landmark 2010 overhaul of the nation's financial regulations and triple the amount donors are allowed to contribute to political parties.
If the spending bill doesn’t pass by midnight tonight, the government will shut down.
Still, the Massachusetts senator called the $1.01 trillion bill that funds the government through September "the worst of government for the rich and powerful" and urged Democrats in the House to vote no unless the language is removed. A vote is expected Thursday afternoon.
"Who does Congress work for?" she said in a floor speech. "Does it work for the millionaires, the billionaires, the giant companies with their armies of lobbyists and lawyers? Or does it work for all of us?"
The vote could serve as a key test of Warren's influence within the Democratic Party.
Other leading Democrats said they have reservations about the provisions in the bill, indicating that the party's support for the measure could crumble.
Democrats almost helped defeat the spending bill on Thursday. A key procedural vote on a set of rules for debate squeaked by 214-212, which allowed the House to move ahead toward voting on final passage of the measure. All 196 Democrats voted no, joining 16 conservative Republicans. The result is a sign there is a narrow road to passage for the government funding bill.
House Minority Leader Nancy Pelosi (D-Calif.) said in a statement Wednesday the provisions in the bill should be removed because they "are destructive to middle class families and to the practice of our democracy."
Support from Democrats could prove critical to passing the legislation and averting a government shutdown. Republicans could lose votes over the fact the spending bill does not include language defunding the president's executive action on immigration.
But other Democrats predicted their party would hold its nose and deliver enough votes to pass the measure. If this bill fails, that could force Congress to pass a temporary spending measure and have another government funding fight next year, when the GOP will control both chambers of Congress. Some Democrats fear that could produce an even worse deal.
“I think the leadership understands let's not mess with this because if you pull one string out, the whole thing will begin to unravel,” Rep. Jim Moran (D-Va.) told The Hill newspaper. “I think it's a set package at this point.”
"I expect this bill will have bipartisan support and pass," House Speaker John Boehner (R-Ohio) told reporters on Thursday. Boehner noted that Democratic negotiators in the Senate signed off on changes to the derivatives-trading rules.
White House press secretary Josh Earnest said Wednesday there are elements of the package "we’re not going to like" but that President Obama will "consider the whole package" before deciding whether to sign it.
After Thursday's close procedural vote, however, the White House came out in support for the funding bill. That could undercut a potential Democratic revolt on the final vote.
Warren's drive against the funding measure is once again fueling talk about whether she'll run for president in 2016 as a liberal challenger to Hillary Clinton.
The senator has emerged as a leading populist voice in the Democratic Party. And her anti-Wall Street message could have resonance with voters.
Just 64 percent of Americans believe it's possible to start out poor and become rich through hard work, according to a New York Times poll released this week. That's eight percentage points lower than in early 2009, right after the financial collapse. Thirty-five percent said they have confidence in Wall Street bankers, with just 4 percent saying they have "a lot" of confidence.
The Progressive Change Campaign Committee, a pro-Warren group, announced Thursday it is asking its members to call lawmakers and urge them to oppose the spending bill.
"Democrats lost in 2014 because they failed to inspire Americans with bold ideas that would tangibly improve people's lives," Adam Green, PCCC's co-founder, said in a statement. "One thing is for sure during the budget negotiations: Easing regulations on big Wall Street banks and gutting campaign finance laws would represent Democrats marching in the exact wrong direction."
But there are doubts about Warren's viability as an alternative to Clinton. A CNN/ORC poll from late November found Clinton leading Warren 65-10 percent among self-described Democrats. Warren's support is particularly low among female and non-white Democrats, two key groups in President Obama's coalition.
