Between the Super Bowl hype and the Super Tuesday hype, I haven't seen any networks cover this, but Super Tuesday is also Fat Tuesday, a popular holiday throughout America. Although Louisiana's primary isn't part of the 22, there are still plenty of people who will be voting drunk. It's probably a good omen for the Fat Cats.
Fox did indeed link their Super Tuesday coverage with their Super Bowl coverage on Sunday morning. It didn't make much sense to me, but it probably gave a bit more exposure to the usual parade of policy wonks and talking heads who were now suddenly supposed to look cool delivering football metaphors about Hilary Clinton.
And, of course, the day after Super Tuesday is Ash Wednesday, the first day of Lent, which millions of Catholics celebrate by freaking out their co-workers.
(I stole that joke from Tina Fey: it's still one of my favorites).
