Though Alaska Gov. Sarah Palin (R) didn’t have any obvious stumbles at Thursday’s debate, she did sound confused when she said there’s a “toxic mess on Main Street that’s affecting Wall Street,” notes Josh Marshall. Pundit Cokie Roberts exposed her ignorance when she called Sen. Joe Biden’s (D-Del.) use of the term “Bosniaks” a gaffe since it’s actually the proper term for Bosnian Muslims, writes Marshall.
