Former Minnesota Governor says government will target any independent who gets close to White House Former Minnesota Governor Jesse Ventura caused shockwaves during a national radio interview today when he warned Barack Obama to be wary of a potential assassination attempt, saying that the government would target any independent politician who got close to the White House. The last chapter of Ventura's new book, Don't Start The Revolution Without Me, is a fictional tale about an assassination attempt on his life following a run for President. The context of Ventura's warning was a discussion about new evidence concerning the assassination of Robert Kennedy, after it emerged that there were additional shooters to accused assassin Sirhan Sirhan. "I believe very strongly that if an independent candidate like myself - a rogue - were to get into the President's race legitimately, if the polls looked like he had a chance to win, I believe that candidate would either be physically assassinated or would be assassinated credibility-wise or in some manner by our government because I do not believe they would ever allow a true independent or a citizen to become President of the United States," Ventura told The Alex Jones Show. "I say this in all seriousness - watch out Barack Obama," he added. Ventura is not the first to warn of a potential future assassination attempt on Obama - British Nobel Prize winner Doris Lessing said Obama would be taken out if he became President in February. "He would probably not last long, a black man in the position of president. They would kill him," Lessing told a Swedish newspaper. Princeton University political science professor-Melissa Harris-Lacewell echoed the same sentiment a month before, saying: "For many black supporters, there is a lot of anxiety that he will be killed. It is on people's minds." "You can't make a prediction like this - like he has a 50 per cent chance of getting shot." "But the greater his visibility and the greater his access to people, there is a danger." Some speculated that Obama had been set up for an assassination attempt during a February 20 rally in Dallas, after it emerged that Secret Service gave the order to stop screening for weapons a full hour before the event began.
