"Politifact" reviews lies, distortions, pants-on-fire lying by McCain.
I'm sure one can find similar items in Obama's campaigning -- indeed, I think PolitiFact itself does if you explore the website -- but of course, a) it's not like I think O's a saint, and b) saying everyone who may be president tells outrageous lies is not a defense, it's a cause for seppuku.
But seriously: ew, just, just, ew. Jonny Mac should be ashamed of himself; if he ever did think of himself as an honorable politician or a reformer, he shouldn't now. But I guess if you spend that much time up Bush's ass, you're bound to end up covered in shit.
