So the fact that a bunch of conservative groups are pointing out some glaring irregularities on Jesse Jackson's tax returns doesn't mean the irregularities don't exist. But the most salient point is that this is the media's fault. It is precisely because the press has treated Jackson as if he were an apostle that the American Conservative Union and other groups felt the need to step into the breach and commit journalism on their own. Incredibly, Jackson gets quoted respectfully when he says Holocaust victims were targeted in Florida, and he's given a forum whenever he wants to hype a mythical lynching. It wasn't until these right-wing conspirators made a fuss that Jackson was forced to explain why his subsidized mistress was missing from his tax returns.
Conspiracies are by definition secretive and sinister.
Here, the secretive part is hard to understand since these groups have used public courts and press conferences to level their charges. That's a bit of stretch from a smoke-filled Star Chamber. Calling this a conspiracy is like saying David Letterman has been secretly telling Bill Clinton jokes behind the ex-president's back. As for the sinister part, well that's a bit more subjective. So the fact that he sees the current effort to get to the bottom of his finances as sinister is not the least bit shocking.
