The MySpace site of John McCain has been manipulated to make it appear as if he supports lesbian marriage.

Mike Davidson, a web publisher and writer, has claimed responsibility for the prank.

A message was placed on the website supporting gay marriage.

It read: “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.”

McCain, a Republican Senator and presidential hopeful, has a record of “U-turns” on gay issues.

At 70, he is the oldest candidate for the Presidency and would be the oldest person to be elected to the office if he won the election in 2008.

Davidson claims that McCain’s camp hijacked HTML code from his website to create a template for the McCain site.

On his own website, Newsvine, Davidson said: “You see, John McCain’s people commandeered my world-renowned MySpace design template, they did not credit me for the template, even though the template explicitly requested credit. They used my own unmodified imagery, specifically for the “Contacting John McCain” table.

“As if that wasn’t bad enough, the McCain crew is actually pulling their image direct from my server on each page load. So every time someone visits the McCain MySpace page, my bandwidth is being used to deliver part of the page! Bad McCain!”

Davidson claims that because no servers but his own were touched, no laws have been broken.
