Outliving His Usefulness?

Eric Fettman theorizes about the newly critical coverage of John McCain:

Fact is, McCain has outlived his usefulness to those on the left.

As long as he was the fly in the GOP ointment - a weapon against President Bush - he was worshiped as the kind of Republican who might actually have been allowed to defeat Jimmy Smits on "West Wing."

Now, however, he's a different kind of Republican - one whose current strong poll numbers spell trouble for Hillary Clinton's coronation.

Fettman's right. I'm not a huge McCain fan (his stands on immigration, the torture amendment, and campaign finance reform are some of the reasons why), but it's impossible not to marvel at the fickleness of the press corps' affections, or the transparency of their agenda.
