A "pretty great" site is right. Political Wire points to this online toy, the "2016 Campaign Television Tracker," which does precisely what it sounds like it does: It tracks television mentions of each presidential candidate on the major networks.
One can filter for candidate and broadcast outlet; for example I just learned that Jeb Bush, on 8/26, was mentioned 71 times by Fox News and 126 times by MSNBC. A rough parity.
Donald Trump? Either Fox News' embarrassment or MSNBC's glee is showing, I'm not sure which. On 8/26, MSNBC mentioned Trump 794 times, while Fox came in with only 295 mentions. The day before, MSNBC mentioned him 579 times, and Fox, a mere 119.
Oh, and on 8/26 and 8/25, Gov. Jindal zeroed out on both networks.
Don't let 'em get you down, Booby. We still need you, baby. A Republican presidential season unanchored by your moral guidance just wouldn't be the same.
