Minnesota campaign finance regulators' database isn't adding up

The Minneapolis Star Tribune reports that the online files from the Minnesota agency charged with tracking candidate and campaign fundraising are riddled with inaccuracies, leading to errors that total as much as $20 million over the past decade, according to an analysis. About 7,000 records of donations between Minnesota groups are incorrect — an error rate of about one in seven. The flaws are enough to hamper any comprehensive attempt to examine the flow of political money in the state, at a time when that spending has soared to record heights.
