If Lindsey Graham is against it, I’m for it.
That said, I don’t like the media deciding whom the voters get to see and whom they don’t. An idea that won’t be adopted would be to take all the officially-declared candidates at a certain cutoff date, randomly assign them to manageable-sized groups (six or so), and hold a series of candidate forums.
What is the alternative? Either the media decides (somehow) or some other entity decides (somehow), who will appear via the media's programming.
