Ouch -- Kerry's Obama endorsement a major diss

John Kerry went to John Edwards' home state the other day to endorse someone else in the Democratic presidential race: Barack Obama.

A major-league diss? Yes. A surprise? Hardly.

Our colleague James Rainey recently spent time with Kerry to produce a rich piece updating the activities -- and aspirations -- of the 2004 Democratic presidential nominee. And following Kerry's implicit rejection of Edwards, he offered these thoughts:

Kerry's relationship with Edwards has been strained since early in the last presidential race, when the younger and more naturally gifted pol threatened, first, to overtake Kerry during the primaries and, then, to overshadow him in the general election.

Edwards never embraced the traditional role of the VP candidate as attack dog on the opposite ticket, Kerry's team believed. They also felt Edwards never deferred to the top of the ticket. "I had to constantly call their road show and remind them that Edwards was running for vice president, not president," said one top Kerry aide.

Almost immediately after the election loss, Edwards began campaigning for 2008, breaking a pledge Kerry believed he'd secured that Edwards wouldn't run until Kerry had decided on another try. A close friend said Kerry seethed about what he believed was a betrayal. For his part, the Massachusetts senator declined last month to discuss his relationship with Edwards: "I don't know where all this stuff comes from. All that stuff is in the past. I want to move on."

And so he has, tying at least a portion of his political fortunes to Obama.

The Bloomberg watch

The off-again-maybe-on-again-maybe-I'm-not-saying-today potential presidential candidacy of New York Mayor Mike Bloomberg took on some credibility the other day.

Associates of the mayor told the Associated Press that Bloomberg, a billionaire several times over, has begun expensive cross-country detailed polling and sophisticated voter analysis in all 50 states as part of his careful, not-so-secret consideration of a White House bid, presumably as an independent.

"They want a hard-headed sense of their chances," said Doug Schoen, who ran Bloomberg's voter database efforts for his two mayoral campaigns.

As if two New Yorkers running to run the country weren't enough.

Ron Paul, loser again

For months now, Ron Paul supporters have been saying the media, the polls and the prognosticators were all wrong. There was a conspiracy.
