Where's McCain?

Since all of the other major players have dropped from the race (or minimally the media radar- sorry Ron Paul), John McCain is harder to find than a lone man with a white striped shirt in a large crowd. While in the long run it may prove to be a benefit to sit back and watch Hillary and Obama take each other down, the fundraising capabilities of each of these candidates cannot be denied. So while the Democrats are traversing the country raising money and promising to spend even more, McCain is telling everyone his life story, a story that, over so many years, must be long and drawn out.
Although I would be perfectly happy watching any and all of these candidates self-destruct, I am wondering how well this strategy will pan out for McCain in the long run of the general election and why nobody from his campaign has remedied or addressed this point. Security in the Primary may feel good for immediate gratification, but I can't remember the last time I saw anything useful about McCain on the news.
Universal health care anyone?
