BEAVERTON, Oregon (CNN) – What just a week ago was a joint attack on Hillary Clinton and John McCain over the proposed gas tax holiday is now just an attack on McCain - in fact, nowhere in his opening words did Barack Obama utter the word "Clinton."
"McCain," on the other hand, was tossed out nine times in the prepared comments.
The Illinois senator called the presumptive Republican nominee "dead wrong" when it comes to comments he made about the economy under the Bush administration, and he even took a swipe at McCain's healthcare plan - an issue that has not traditionally been used as a means to contrast himself from the Arizona senator.
"John McCain wants to continue a George Bush approach that only takes care of the healthy and the wealthy," Obama said.
During a question-and-answer session, however, Obama was asked what he thought about the idea of picking Clinton as his running mate. The White House hopeful repeated his standard response: that he has "not won this nomination yet" and that the two Democrats are still "actively running."
"She is very smart, and so I think she would be on anyone's…short list of vice presidential candidates," Obama said. "But beyond that I don't want to offer an opinion."
