In the ongoing Senate debate on the Democracy for All Amendment, a proposed constitutional amendment that would overturn decisions like Citizens United, Sen. Ted Cruz has taken to waving around a list of top political donors that ranks Koch Industries as the 58th largest donor. But what Cruz has not been saying is that this list, compiled by our friends at the indispensable Center for Responsive Politics, has — by its own admission — a big piece of the puzzle missing.

The list details “heavy hitters,” organizations that have sent large amounts of money to candidates, parties, and PACs between 1989-2014. But the list points out that it doesn’t include dark money or other outside spending, such as money given to a super PAC. In the article’s own words:

It’s also important to note that we aren’t including donations to politically active dark money groups, like Americans for Prosperity, a group linked to the Koch brothers, or the liberal group Patriot Majority — because these groups hide their donors; see a list of top donors that we’ve been able to identify to such groups. We are working to revise this list to take into account the new realities of campaign finance created by the Citizens United decision, but as it currently stands, there are significant omissions.

When you do take into account outside spending, which exploded in the wake of the 2010 Citizens United decision, the picture changes dramatically. For example, the Koch-backed network raised more than $400 million in 2012 alone — a figure that towers over the $19.7 million in Koch Industry’s direct contributions over a 25-year period to candidates, parties and leadership PACs noted on the list Cruz references. In fact, the $407 million they funneled into 2012 political activity alone is more than the top six organizations on the list have sent to candidates, parties, and PACs in the past 25 years combined. And as Washington Post reporter Matea Gold noted earlier this year, “[T]he network of politically active nonprofit groups backed by the Kochs and fellow donors in the 2012 elections financially… matched the long-established national coalition of labor unions.” To put it simply: when you look at the full landscape of political spending, it would be difficult to argue that the Koch-backed network is not among the top “heavy hitters” in our democracy.

Sen. Cruz can continue to cherry-pick the stats he finds most convenient for his quest to block meaningful Congressional action on big money in politics, but the American people know better.
