Veteran Republican political consultant, unrepentant dirty trickster, and recently reborn libertarian Roger Stone yesterday published a startling accusation against Paul Ryan and Mitt Romney on his personal website, The Stone Zone. According to Stone, the billionaire Koch brothers purchased the Republican vice presidential nomination for Ryan from Romney in late July by promising to fork over an additional $100 million toward “independent expenditure” campaigning for the GOP ticket.

Any such transaction would represent a serious violation of federal election laws and perhaps other statutes, aside from the ethical and character implications for all concerned. Although Stone is not the most reputable figure, to put it mildly, he has been a Republican insider, with access to the party’s top figures, over four decades.
