Senator Elizabeth Warren (D., Mass) and House Democrats have picked a curious place to pick a fight with Republicans and President Obama that could result in a government shutdown: a Dodd-Frank policy change that received significant Democratic support earlier this year.

The Dodd-Frank rider is “an unremarkable and minor reform that is being demagogued by Elizabeth Warren,” according to one House Republican.

How unremarkable? It passed the House Financial Services Committee on a 53-6 vote. There are 27 Democrats on the committee.
