@derickflorian Third parties would benefit more from using any other system than first past the post voting (I'm a single transferable vote person myself, but I know that is a pretty complex system both to implement and for voters to understand.)
It is in fact not political speech I want to tax, but in means of amplifying that speech (buying TV time, printing mailers, paying phone bank callers.) Local candidates who go to public spaces and talk to voters should be able to do so without impediment, but when every second ad is for #prop27, yeah I want some social benefit from that mess.
