Arizona's and Michigan's primary happened Tuesday night, and like many other political pundits, Jon Stewart is experiencing some pre-Super Tuesday fatigue. CNN, MSNBC, and Fox called Arizona early for Romney, meaning that the rest of the night's tired coverage was devoted to much closer race between him and Santorum in Michigan, even though the final vote count doesn't really matter since delegates in the state are divvied up proportionally. How did the cable news networks buy time? By inanely debating the difference between a "home" and "native" state and having Anderson Cooper walk around CNN's studio.
