But he's still John Kerry. And he's still capable of whacking his fellow candidates for supporting the Iraq-war resolution even though he, too, supported it. Anne Kornblut and Patrick Healy report in today's Boston Globe:

Kerry yesterday launched a new attack against Gephardt and Senator Joseph I. Lieberman of Connecticut over their support for the 2002 resolution authorizing the use of force in Iraq. Kerry accused the two of siding with President Bush on the resolution, ultimately approved by Congress, instead of an earlier one that would have limited Bush's ability to go to war quickly.

"When Joe Lieberman and Dick Gephardt wound up down at the Rose Garden with the president signing off on some deal, they pulled the rug out from the rest of us in the United States Senate who were fighting for a different resolution," Kerry told voters in Guttenberg, Iowa. Kerry ended up voting for the resolution that passed.

For what it's worth, Kerry has also slipped backwards in Zogby's Iowa tracking polls for the first time in a while.
