OpenSecrets.org tallied the top donors in federal elections between 1989 and 2014. Koch Industries -- privately owned by the Evil Koch Bros -- is on the list, to be sure, but doesn't appear until the 59th slot, with $18 million in donations, 90 percent of which went to Republicans.<p>So who occupies the 58 spots ahead of the Evil Koch Bros? Six of the top 10 are ... wait for it ... unions. They gave more than $278 million, with most of it going to Democrats.<p>These are familiar names: AFSCME ($60.6 million), NEA ($53.5 million), IBEW ($44.4 million), UAW ($41.6 million), Carpenters & Joiners ($39.2 million) and SEIU ($38.3 million).<p>In other words, the six biggest union donors in American politics gave 15 times more to mostly Democrats than the Evil Koch Bros.<p>Three of the remaining four slots in the top 10 were taken by AT&T ($56.4 million), National Association of Realtors ($51.2 million) and Goldman Sachs ($44.8 million).<p>So, if money is the measure of evil in American politics and the Evil Koch Bros only come in 59th, who is really the most evil donor ever?<p>Turns out it's the left-wing group, Act Blue, with just short of $100 million in contributions during its lifetime, which only started in 2004, 15 years after the Evil Koch Bros in the OpenSecrets.org compilation.
