....The evidence, presented to the public in the form of affidavits that will be used in McDaniel’s forthcoming official challenge of election results, is hundreds of pages long and encompasses nearly every one of Mississippi’s 82 counties.
At the press conference, McDaniel announced he will be using such evidence to file a formal challenge of the runoff results with the state GOP executive committee. Ten days after he files the challenge with that body—which, given its extensive ties to the GOP establishment in the state, is expected to rule against the Tea Party-backed McDaniel or just simply ignore the challenge—McDaniel can take the challenge into state court.
“It’s been an interesting six weeks since the 24th. We’ve been very, very busy. We’ve covered the state as well as we could with hundreds of volunteers, but justice has no time table, and yet here we stand. They asked us to put up or shut up—well, here we are. Here we are with the evidence,” McDaniel said.
Affidavits of what? More people swearing they voted for him than the number of votes he got in the official election numbers?
