Nate Silver has already dubbed the 2014 election as "the least important in years." But this year's midterms are still breaking records for at least one thing: Secret political spending.
A historically unprecedented amount of dark money has already been spent to influence the outcome of the elections. As of July 15, more than $34 million in dark money had been spent on the 2014 election cycle. That is more than 15 times the $2 million–plus in dark money spent at this point in the 2010 midterms, and three times the $11 million in dark money spent at this point in the 2012 elections.
Dark money means political spending where the identity of the underlying source of the funds is not public. The Supreme Court's Citizens United decision in 2010 allowed new political spending from corporations, and subsequent decisions removed limits on so-called independent spending. Now, sophisticated political players who want to exercise power without accountability are channeling their political spending through 501(c)(4) "social welfare" groups that aren't required to disclose their funders.
