WASHINGTON – The White House and Republicans kept up the unrelenting mudslinging Sunday over who's to blame for roundly condemned budget cuts set to take effect at week's end, with the administration detailing the potential fallout in each state and governors worrying about the mess.

But as leaders rushed past each other to decry the potentially devastating and seemingly inevitable cuts, they also criticized their counterparts for their roles in introducing, implementing and obstructing the $85 billion budget mechanism that could affect everything from commercial flights to classrooms to meat inspections. The GOP's leading line of criticism hinged on blaming Obama's aides for introducing the budget trigger in the first place, while the administration's allies were determined to illustrate the consequences of the cuts as the product of Republican stubbornness.

Former Republican National Committee chairman Haley Barbour, aware the political outcome may be predicated on who is to blame, half-jokingly said Sunday: "Well, if it was a bad idea, it was the president's idea."
