This Rasmussen poll showing that by a 58 percent to 30 percent margin Americans believe Obama denounced Jeremiah Wright for political convienience, may be the most troubling poll I’ve yet seen for the Illinois senator. To win, Obama has to be able to convince people that he will be able to change Washington and transform its politics. Since he has a very thin public record, and no serious accomplishments he can point to in order to demonstrate he is capable of fulfilling this promise, he is asking voters to trust his words. If — to borrow a favorite word of Obama’s — voters have become too cynical, and now are beginning to view him as any other politician, on what basis can he make an appeal to voters? You expect people to take a leap of faith, if they don’t have faith in you.
