Union Power

I'm a big proponent of allowing anyone to use their property in any (non-rights-violating) manner they desire, including for political speech, but I think this tidbit from a City Journal article on the California Teacher's Association might give pause to some of my opponents on this point:

According to figures from the California Fair Political Practices Commission (a public institution) in 2010, the CTA had spent more than $210 million over the previous decade on political campaigning—more than any other donor in the state. In fact, the CTA outspent the pharmaceutical industry, the oil industry, and the tobacco industry combined.
