The most important remaining battle to rein in Wall Street is over Senator Blanche Lincoln’s measure to stop the big banks from being subsidized by taxpayers for their risky derivative trades. Miraculously, it’s still in the bill but it’s on life support. The bill has now gone to the conference committee where differences between the House and Senate bills are to be ironed out.

But official Washington (read: dependent on Wall Street for money) is dead set against it. Even Barney Frank — who Massachusetts voters used to consider a reliable progressive until he became chair of the House Financial Services Committee — has vowed to kill Lincoln’s provision. And the White House says the measure is “not core,” which in Washington-lingo means “you’re free to dump it.”

Big, big money is at stake.  Wall Street’s five largest banks have a corner on the trade, raking in about in about $30 billion in over-the-counter derivatives last year. It’s the single largest reason they’re too big to fail. So they’re spending like mad on Washington lobbyists and campaign donations in order to keep the subsidy in place. (Lincoln’s provision doesn’t force them to give up derivative trading, by the way; it only forces them to do it in a separate entity that doesn’t get subsidized by deposit insurance or the Fed’s discount window).

All the guns are aimed at this measure. But it’s still possible that the people can prevail, if we’re organized and active. Here’s a list of all the Dems on the Senate Banking and House Finance Committee, as well as Republican conferees. All conferees are indicated by ->.

Organize and mobilize your friends and acquaintances, especially those who live in these states or districts, to call their members and make their voices heard. Tell them you want Lincoln’s measure (Section 716 of the Senate bill) to remain in the final bill. Say you’ll hold them responsible if it goes.
