US - Congress' approval rating the lowest in history

That would be the Democrat controlled congress.

"Democrats have created a monster for themselves, and they seem unable to free themselves from their rut. They have accomplished almost nothing of their agenda, save a minimum-wage hike. They have punted on Iraq, surrendered on FISA and the TSP, and have allowed themselves to get outmanuevered on immigration. They have spent hundreds of hours on investigations to no real benefit while legislation languishes. Their so-called ethics reforms have done nothing but allow lobbyists even more ways to influence Congress, and earmarks are murkier than ever."
