Spout your favorite buzz phrase all you want, voting for McCain isn't going to change crap. He believes exactly the same thing despite his hypocritical cries of "socialism". The reality is our tax system is massively out of balance, the wealthy enjoy huge protections from the government (aww, you gambled and lost money? Here's a bailout!) and pay a small percentage of their income. Both Obama and McCain have called for fixing that balance.
John McCain: “We feel, obviously, that wealthy people can afford more… I believe that when you really look at the tax code today, the very wealthy, because they can afford tax lawyers and all kinds of loopholes, really don’t pay nearly as much as you think they do when you just look at the percentages. And I think middle-income Americans, working Americans, when the account and payroll taxes, sales taxes, mortgage pay — all of the taxes that working Americans pay, I think they — you would think that they also deserve significant relief, in my view… here’s what I really believe, that when you are — reach a certain level of comfort, there’s nothing wrong with paying somewhat more.”
