Senator McCain's opposition to DADT repeal contradicts his earlier statements

To the surprise of no one:

The Pentagon study that argues that gay troops could serve openly without hurting the military's ability to fight is expected to re-ignite debate this month on Capitol Hill over repealing the 17-year-old "don't ask, don't tell" policy.

Officials familiar with the 10-month study's results have said a clear majority of respondents don't care if gays serve openly, with 70 percent predicting that lifting the ban would have positive, mixed or no results. The officials spoke on condition of anonymity because the findings hadn't been released.

Defense Secretary Robert Gates and Chairman of the Joint Chiefs of Staff Adm. Mike Mullen, who have both said they support repealing the law, were scheduled to discuss the findings with Congress Tuesday morning and with reporters Tuesday afternoon.

Republicans, led by Sen. John McCain of Arizona, have mostly opposed repealing the law because they say efforts to do so are politically driven and dangerous at a time of two wars.

It's interesting that McCain would take this tone. In 2009, he said the following:

My opinion is shaped by the view of the leaders of the military. The reason why I supported the policy to start with is because General Colin Powell, who was then the Chairman of the Joint Chiefs of Staff, is the one that strongly recommended we adopt this policy in the Clinton administration. I have not heard General Powell or any of the other military leaders reverse their position, just like when on other issues, that people are expert and knowledgeable of, I rely on their opinion. But this is unique. These military leaders are responsible for the very lives of the men and women under their command, and that's why I am especially guided, to a large degree, by their views.

And in 2006 (via John Aravosis of Americablog), he said:

And I understand the opposition to it, and I've had these debates and discussions, but the day that the leadership of the military comes to me and says, Senator, we ought to change the policy, then I think we ought to consider seriously changing it because those leaders in the military are the ones we give the responsibility to.

Seems to me that McCain is ducking and dodging.
