WASHINGTON — A large share of the presidential primary season debates will not be aired on free over-the-air broadcast networks. Of the 15 primary season debates, all but five will air on cable TV. That pattern has led Susan Crawford, a Harvard University law professor, to question whether there is something terribly wrong here. Crawford published a piece last week in Medium about the cable subscription fees necessary for interested voters to watch the debates in real time. She said it amounts to nothing short of a poll tax.
