This time, he appears to be going after Gore and Kerry.

In a speech this afternoon in central Iowa, Barack Obama seems to have widened his criticism of the politics of the past to encompass not only Hillary Clinton but John Kerry and Nobel Laureate Al Gore. Making an argument for his electability, Obama said, “I don’t want to go into the next election starting off with half the country already not wanting to vote for Democrats — we’ve done that in 2004, 2000,” according to a person at the event.

The first comment to the post says it very well, “His arrogance and sense of entitlement are not just inaccurate, his remarks are insulting and stupid.”(emphasis mine)

I would add that Al Gore got more votes than George Bush, and the problem with both campaigns is that they were unwilling to call out George W. Bush specifically, and the Republicans generally for their incompetence and corruption.

You also have Barack Obama going after Labor Unions political involvement:

And top union officials who support Obama’s rivals are in turn accusing the Illinois Democrat, who once sought their endorsements, of trying to damage labor’s political role. “I’m taken aback that somebody like Obama would think that Oprah Winfrey has a greater right to participate in the political process than the 4 million people I represent,” Edward J. McElroy, the president of the American Federation of Teachers, which has spent $799,619 on New York Sen. Hillary Rodham Clinton’s behalf, said, referring to the television host’s high-profile support for Obama. “It’s sour grapes. It sounds just like the charges the Republicans make.”

It appears that there is no Democratic constituency that he is unwilling to “Sistah Soljah”.
