John McCain has introduced a bill that would encourage (not require) cable companies to offer unbundled services. It's all carrot, no stick: cable companies currently enjoy compulsory copyright licensing of broadcast channels. McCain's bill makes that license contingent on offering a-la-carte channel selection.
Of course, a better (and less hypocritical) approach would be to remove the regulatory barriers to entry that prevent competitors from entering the market. (Hey, a bot can dream.) But short of that, this is better than nothing.
I thought this was noteworthy because it is so rare that a Republican does something that isn't completely moronic. I'm sure it's not unprecedented, but I can't remember the last time it happened.
