On Sunday, he said on national television that to solve Social Security “everything’s on the table,” which of course means raising payroll taxes. On July 7 in Denver he said: “Senator Obama will raise your taxes. I won’t.”

This isn’t a flip-flop. It’s a sex-change operation.

What I’m asking is, does John McCain have the mental focus, the intellectual discipline, to avoid being out-slicked by Barack Obama, if he isn’t abandoned by his own voters?

It’s not just taxes. Recently the subject came up of Al Gore’s assertion that the U.S. could get its energy solely from renewables in 10 years. Sen. McCain said: “If the vice president says it’s doable, I believe it’s doable.” What!!?? In a later interview, Mr. McCain said he hadn’t read “all the specifics” of the Gore plan and now, “I don’t think it’s doable without nuclear power.” It just sounds loopy.

There is a reason the American people the past 100 years elevated only two sitting senators into the White House — JFK and Warren Harding. It’s because they believe most senators, adept at compulsive compromise, have no political compass and will sell them out. Now voters have to do what they prefer not to. Yes, Sen. McCain has honor and country. Another month of illogical, impolitic remarks and Sen. McCain will erase even that. Absent a coherent message for voters, he will be one-on-one with Barack Obama in the fall. He will lose.
