I've noticed in the past few weeks that Obama seems to be taking the current administration's strategy used in the runup to the Iraq war on John McCain.  If you can remember, in 2002 and early 2003, you never heard the word Iraq without hearing 9/11, Al-Quaeda, or Osama Bin Laden in the same paragraph if not the same sentence.  Although no one can speak to the actual intent of the individual's in the administration, a reasonable person could conclude that the goal was to conflate the issues in order to garner support for the invasion of a country that had never attacked the United States.

Evidence from intelligence sources, secret communications and statements by people now in custody reveal that Saddam Hussein aids and protects terrorists, including members of Al Qaida." -- State of the Union Address (1/28/2003)

"After the chaos and carnage of September the 11th, it is not enough to serve our enemies with legal papers. The terrorists and their supporters declared war on the United States, and war is what they got. Some in this chamber, and in our country, did not support the liberation of Iraq. Objections to war often come from principled motives. But let us be candid about the consequences of leaving Saddam Hussein in power. We're seeking all the facts. Already, the Kay Report identified dozens of weapons of mass destruction-related program activities and significant amounts of equipment that Iraq concealed from the United Nations." --- State of the Union Address [6] (1/20/04)

Currently, in order to make the case that McCain=Bush you rarely hear Obama mention McCain without mentioning George W. Bush in the same paragraph if not the same sentence.

For example when replying to McCain's statement that we are currently back at pre-surge levels in Iraq:

"That's not true, and anyone running for Commander-in-Chief should know better. As the saying goes, you're entitled to your own view, but not your own facts. We've got around 150,000 troops in Iraq - 20,000 more than we had before the surge. We have plans to get down to around 140,000 later this summer - that's still more troops than we had in Iraq before the surge. And today, Senator McCain refused to correct his mistake. Just like George Bush, when he was presented with the truth, he just dug in and refused to admit his mistake. His campaign said it amounts to "nitpicking."

And Axelrod counter-punches on Obama's supposed lack of credibility on Iraq:

"We are talking on a day where the president's press secretary released a book where they frankly acknowledged that they engaged in deception and propaganda to essentially lead America to war. Senator Obama saw through that and raised the appropriate questions. Sen. McCain didn't"

I for one think it is a great strategy, even though it comes from the wrong side of the aisle.  It has been proven to work and provides some comeuppance for the people in government that worked with all their heart to have this disasterous war waged.
