John McCain's webiste was the victim of some rather primitive "hacking", that made the presidential hopeful seem like he supported lesbian marriages.
"Hacking" is a bit of an overstatement. Whoever was behind the myspace had utilised code written by web publisher Mike Davidson. The code explicitly required anybody using it to credit Davidson. Additionally the Republican was committing the most heinous of cybercrimes, bandwidth theft. In Davidson's words, "Bad McCain!"
Davidson just changed his own code so that McCain's website now said something a lot of guys (but not uptight Republican senators) might say: "Dear Supporters, today I announce that I have reversed my position and come out in full support of gay marriage... particularly marriage between two passionate females."
Classic "old school" pranking.
