The Arizona Republican with a reputation as a maverick has seemed to go back on earlier stands. In an interview, he says he's unchanged.
What has happened to John McCain?
This month, the Arizona Republican reacted angrily when the chairman of the Joint Chiefs of Staff came out for scrapping the military's "don't ask, don't tell" rule on homosexuals -- even though McCain earlier said he'd follow the commanders' advice on the issue.
Before that, McCain voted against a bipartisan proposal for a deficit reduction commission, even though he initially was one of the measure's co-sponsors. The vote was a jab at President Obama, who had endorsed the idea to show that he was serious about reducing the deficit.
So has McCain, the Republican maverick who bucked his party's leaders to launch bipartisan legislation on campaign finance reform, turned back into a partisan conservative?
Not really. He's always been a partisan conservative -- most of the time.
