Dick Morris shows how it's done:

Fox turned out to be a perfect fit for Morris. He could make the sort of wildly off-base claims he was famous for as a consultant, only no one would remember if, say, he predicted, on the eve of the 2000 election, that Hillary Clinton would lose her Senate race (she did not) or claimed that Arkansas was “leaning Obama” in 2008 (the state went for McCain by 20 points). A few months into Obama’s presidency, however, Morris branched out from wrongheaded prognostications and into the outlandish conspiracy theories that were then fueling the nascent Tea Party movement. On Fox, he declared that “those crazies in Montana who say, ‘We’re going to kill ATF agents because the U.N.’s going to take over’well, they’re beginning to have a case.” He pushed the rumor that House Democrat Eric Massa, who was under investigation for sexual harassment, was being targeted as retaliation for voting against health care reform.

Before long, Morris had mastered the art of being a Tea Party celebrity.
