McCain already in full Obama-bashing mode

Big headlines this weekend about John McCain’s attack ad based on Barack Obama canceling an appearance with U.S. military personnel in Germany. The voiceover says: “He made time to go to the gym but canceled a visit with wounded troops. Seems the Pentagon wouldn’t allow him to bring cameras.” First, those abs won’t crunch themselves. Second, if Obama had visited the troops and cameras were rolling, that would’ve been a great photo op, so why is McCain complaining? Third, and most important: Isn’t it a tad early—before either party’s convention—to “go negative”? Maybe I’m just naive.
