Here's the thing about stories, they get old, if the Obama-Rezko connection stories didn't take the first time around, they aren't going to pick up any traction when they get rehashed, unless there's something new.

Obama has the message that people want to hear, why do you think he draws huge crowds, and millions of contributors.

In the Great Depression, FDR's theme song was "Happy Days are here again", it worked.

Hillary Clintons got more facts and figures in her stump speech, but not enough of what people really want, and McCain is telling people what they don't want to hear.

People want change, every candidate claims to be the agent of change, but Obama rings true to more people.
What's going to happen between now and November to change that equation?
Iraq will still be a disaster, the economy will still be reeling and the alternative to Obama will be the Old Geezer, who wants to stay in Iraq for a hundred years, and will only look older than the pyramids in the debates.

And with all this desire for change, the big selling point for McCain is that he can use the veto to block the Congress and prevent change.
And McCain will have the endorsement of a President with 19% approval ratings, how do handicap that race?
