Senator Barack Obama's campaign has launched a website designed to refute lies and smear allegations spread by his opponents.

Called Fight the Smears, the site looks to neutralise rumours spread from television, the Web, radio and seemingly most pervasively, by email.

"The Obama campaign isn't going to let dishonest smears spread across the internet unanswered," said Obama campaign spokesman Tommy Vietor. "Whenever challenged with these lies we will aggressively push back with the truth and help our supporters debunk the false rumors floating around the internet."

The Washington Post said that such an internet campaign is virtually a "must have" for the black presidential nominee due to the number of untrue rumours swirling around the blogosphere and other media alleging that he is of the Muslim faith and attended a madrassa (religious school) during his time in Indonesia.

Other untrue rumours are circulating over his alleged lack of patriotism and the wrong fact that he took the oath of office on the Koran when being sworn in to the Senate.

The attempted smears are coupled with more recent attacks on his wife Michelle when right wing radio host Rush Limbaugh claimed a tape exists of Michelle Obama using the term "whitey," an allegation the Obama camp denies.

Democratic Rep. Dan Boren, Oklahoma's only Democratic member of the congressional delegation, has refused to endorse Sen. Barack Obama for presidential office.

However Boren has said the Illinois Senator will have his vote both at the Democratic convention in Denver in August and in November on election day.

Calling Obama "the most liberal senator in Congress", Boren criticised his record on working with Republicans saying "it does not reflect working in a bipartisan fashion" and has joined Florida Rep. Tim Mahoney in refusing to endorse the presumptive Democratic nominee.
