republican electorate with his rhetoric. so far polls appear to be backing his up. the question is how long it will last. in a brutal editorial the des moines register is demanding donald trump pull the plug on his, quote, bloviating side show calling him a feckless blow hard who can generate numbers not by provoking thought, but by provoking outrage. his republican competitors agree. >> he's becoming a jackass. >> trump is not apologizing for criticizing john mccain's war service but did some closer than before. >> i supported him. i raced a lot of money for his company against president obama. hopefully i said it correctly .
