Who amongst the political rulers of the country, apart from Jared Polis and Ted Cruz, is fighting against this? I don't mean populists who make vague promises about net neutrality in order to be elected, then put people in place to undermine their promises -- I mean people who are in a position to fight the FCC, and who are actively doing it.
