Kimberley Strassel for The Wall Street Journal, here:
Mr. Reid was quite agitated on the Senate floor about "unlimited money," by which he must have been referring to the $4.4 billion that unions had spent on politics from 2005 to 2011 alone, according to this newspaper. The Center for Responsive Politics' list of top all-time donors from 1989 to 2014 ranks Koch Industries No. 59. Above Koch were 18 unions, which collectively spent $620,873,623 more than Koch Industries ($18 million). Even factoring in undisclosed personal donations by the Koch brothers, they are a rounding error in union spending. ...
[I]n addition to a system in which organized labor spends "unlimited money" to "rig the system to benefit themselves" and "buy elections," (to quote Mr. Reid)[about the opposition], Mr. Obama's IRS has made sure to shut up anyone who might compete with unions or complain about them.
Democrats: The things they are for and against are the things they are against and for.
