Negotiations on Capitol Hill appear likely to ensure a smooth flow of disaster aid in the wake of Hurricane Isaac despite some sniping on the presidential campaign trail.

Congressional aides are working quietly on a six-month government funding bill that would prevent a shutdown of the government next month and ensure that the government's main disaster relief program gets a steady flow of money.

It's a different story from a year ago, when inadequate Federal Emergency Management Agency funding and slew of expensive disasters combined to almost drain the government's main disaster program dry.
