Following up on an editorial Wednesday morning, New York Times editorial page editors say they were getting complaints that the earlier piece didn't explore the "the big financial muscle of unions in backing liberal politicians." Some commenters claimed unions vastly outspend the Kochs politically. Not true, the Times writes. "...Unions poured about $400 million into the 2012 elections. That almost matched the $407 million raised and spent by the Koch network in that same election cycle. But think about what those numbers mean. Two brothers, aided by a small and shadowy group of similarly wealthy donors, spent more than millions of union members. The fortunes of just a few people have allowed them an outsized voice, and they are openly trying to use it to turn control of the Senate to Republicans."
