Rep. Gwen Moore (D-Wis.) has a payday lending problem.

On Tuesday, HuffPost published an article highlighting an obscure piece of legislation moving through Congress that would help payday lenders and other shady operators skirt predatory lending laws passed by state governments. Its the sort of bill Republicans sponsor all the time. Every now and then, Democrats quietly join them, hoping that a minor bill circling through the House Financial Services Committee will be overlooked in the grand legislative debates over taxes, health care and foreign policy.

The bill was introduced by Moore and archconservative Rep. Patrick McHenry (R-N.C.), and it exploits a weakness in national banking law to provide convoluted but very real aid to predatory lenders.
