The Senate could vote again as early as today to attempt to begin consideration of a regulatory overhaul bill.

Lawmakers are trying to break a legislative logjam on the measure, which Republicans and some Democrats contend will allow for taxpayer bailouts of financial firms that are considered too big to fail. A proposal to begin debate was defeated yesterday, mostly along party lines.

The provisions of the measure most impacting credit unions, the creation of a new entity to regulate consumer financial products, have not been among the major sources of controversy.
