Not like a certain someone who "dislikes" Bush & Cheney, and all Republicans, dumping on them at every opportunity, with some of the most vile adjectives he can thnk up now, right?
Truthfully though sirs, this isn't (or shouldn't be) an issue. If it came out tomorrow that McCain gave 0.05% of his income to charity, I could honestly care less. To judge someone's generosity by financial contributions to charity is a myopic view of the situation. There are other ways to give to charity than by just cash. Volunteering, items, and undocumented contributions for example. Personally, I don't write off my contributions, I tend to find it morally disingenuous to give money and then write it off of my taxes. I'm not faulting anyone else who does so, to each their own, but this thing is a tempest in a teapot, because all you're seeing is the contributions listed on his tax return. I'd rather give because I want to give, or believe in that cause, than give because it makes me appear more generous or because it makes a nice write off.
A side story real quick, if you'll allow. As you probably know, I live in a small town (7K) in a rural area. There is one family that is extremely wealthy, they own several businesses in logging, waste management, a machine shop, and now they're investing heavily into composite molding and biofuel. They also give a ridiculous amount of money to local charity, the only reason that I know that is because I served on the boards of a couple. When they gift the money, it is gifted anonymously, with a non-disclosure agreement. As far as I know, they don't claim it on their taxes (why would they do so when they require the charities to keep the source a secret?), which may not be financially wise, but tells me something about their own character.
To pretend that someone, even a Presidential candidate, only gives what is listed on their tax return, is rather foolish.
