In the first three weeks since the election, President-Elect Obama has broken with tradition established over the past either years through his controversial use of complete sentences, political observers say.  Millions of Americans who watched Mr. Obama's appearance on "Sixty Minutes" witnessed the president-elect's unorthodox verbal tick, which had him employing grammatically correct sentences virtually every time he opened his mouth.



But Mr. Obama's decision to use complete sentences in his public pronouncements carries with it certain risks, since after the last eight years many Americans may find his odd speaking style jarring.



According to presidential historian Davis Logsdon of the University of Minnesota, some Americans might find it "alienating" to have a President who speaks English as if it were his first language.



"Every time Obama opens his mouth, his subjects and verbs are in agreement," said Mr. Logsdon.  "If he keeps it up, he is running the risk of sounding like an elitist."  The historian said that if Mr. Obama insists on using complete sentences, the public may find itself saying, "Okay, subject, predicate, subject predicate.....we get it, now stop already."



The President-elect's stubborn insistence on using complete sentences has already attracted a rebuke from one of his harshest critics, Gov. Sarah Palin of Alaska.



"Talking with complete sentences there and also too talking in a way that ordinary Americans like Joe the Plumber can't really do there, I think needing to do that isn't tapping into what Americans are needing also," she said.
