I'd like to see McCain. Ive been on his bandwagon before he became so popular with the media. Sure he's a lier and a typical politician, but I like his candor, and his adherence to basic conservative and classic liberal principles, rather than adhereing to some perverse form of corporate-fascism-imperialism, or middling, politically correct, ineffectual socialism of the current Republicans and Democrats.
