One of Biden's weaknesses

Revisiting Biden's tendency to speak without thinking:

Loose Lips Sink Ships

Over the course of his presidential bid, Biden cemented his reputation as -- how to put this nicely? -- less than disciplined on the campaign trail.

In the summer of 2006, as he was publicly mulling the race, Biden set off a controversy over comments he made about Indian Americans.

"I've had a great relationship [with Indian Americans]," Biden said. "In Delaware, the largest growth in population is Indian-Americans moving from India. You cannot go to a 7-Eleven or a Dunkin' Donuts unless you have a slight Indian accent. I'm not joking."

On the day he formally announced his candidacy, a New York Observer story that quoted Biden as calling Obama "articulate and bright and clean and a nice-looking guy" came out, and the resultant uproar effectively undercut any momentum Biden was hoping to build.

While Biden was on his best verbal behavior for much of the rest of the campaign, there is no question that his tendency to shoot from the lip worries some in Obama world. As one Democratic consultant put it: "You know there will be three days in the campaign where someone in Chicago will get a call and respond -- 'What did you say he said?.'" . . . .

At least Biden doesn't lack for self-confidence:

"I think I have a much higher IQ than you do."

Some Democrats in the media are not too happy with Obama's choice:

The picks say something profound about Obama: For all his self-confidence, the 47-year-old Illinois senator worried that he couldn't beat Republican John McCain without help from a seasoned politician willing to attack. The Biden selection is the next logistical step in an Obama campaign that has become more negative - a strategic decision that may be necessary but threatens to run counter to his image. . . .
