After years of being a Democratic Senator in little more than name, Kyrsten Sinema has decided to drop the name part as well.

Who is Kyrsten Sinema? What has she been doing as a (as of a few hours ago, former) Democratic Senator? What will her leaving the party mean for the balance of power in the US? I discuss all this and a bit more in this (poorly timed – wish she hadn’t picked a Friday/hope my audience has nothing better to do on a Saturday) episode.
