Will the real McCain please stand up?

SEN. JOHN MCCAIN, the fellow who accepted Sarah Palin as his runningmate - remember? - seems to be getting flakier by the minute. While publicly complaining that his Republican party needs to do more to lure Latino voters into the GOP column, he now has declared that he will vote against Sonia Sotomayor because he fears she will legislate from the bench. (A fear, by the way, that has not discouraged his friend, Lindsay Graham, from supporting the nomination.)

Is McCain reclaiming his maverick status, or is he simply silly? The Arizona senator and his attempts at rational thought are often like two ships passing in the dead of night. What does he do now to appeal to the Latino vote in his own state? Or does it really matter?
