All but two Republicans voted for the measure, including all but one  member of the hyper-conservative Freedom Caucus, which frequently  lambasts the grip of "crony capitalism" in Washington. Only 70 Democrats  voted against the measure, mostly members of the Progressive Caucus.

So how did so many lawmakers end up voting to just hand $17 billion to banks?
Congressional negotiators have been scrambling for months to find  potential spending cuts that could offset new funding to fix roads and  bridges. Republicans have refused to consider any tax increases to  support the infrastructure spending, making any potential source of  frivolous spending a target.
Enter the Progressive Caucus. Every  year, the coalition of dozens of Democrats releases an annual budget  proposal. With Republicans in control of the House, it’s a largely  symbolic measure that essentially lays out the priorities of liberal  lawmakers. But the budget  released last year included an item that most members of Congress had  never heard of: "Ending Excessive Fed Dividends For Wall Street." 
The Progressive Caucus had been  studying the Federal Reserve and discovered that the central bank pays  billions of dollars a year in dividends to banks in the U.S. It wasn’t  exactly a secret, but not many people on Capitol Hill knew it was going  on, partly because the practice is so old -- dating back to the creation  of the central bank. Cutting those dividend payments in half would  shift $17 billion from banks to federal coffers.
The measure disappeared for months after the Progressive Caucus  released its budget. But this summer, the Senate picked up the proposal  as a way to help pay for new highway funding. After years of living with  tight budgets from the automatic budget cuts known as the sequester,  there just aren’t that many easy targets for spending cuts in the  federal budget. And the House initially followed the Senate’s lead,  including the dividend cut plan in its original version of the highway  bill.
