The Huffington Post reports that McCain has paid $175,000 to Lincoln Strategy Group, a political consulting group based in Arizona and run by Republican operative Nathan Sproul, who’s been accused of voter registration fraud in several states — in the form of throwing away Democratic registration forms and suppressing Democratic voter turnout.

HuffPost also reports that the Republican National Committee separately paid Lincoln Strategy another $37,000 to register voters for this election. Sproul, meanwhile, has donated nearly $30,000 to the McCain campaign. He’s also a former leader of the Arizona Republican Party and of the state’s Christian Coalition.
