What the hell is that on CNN

On CNN I’m watching the VP debate. There are random “scorecards” on the edges. What the heck? Who are they? Why do I care? Can I get a few seconds to form my own opinion by myself?

Secondly, there’s this crazy “uncommitted Ohio voters” meter that looks like some wall street ticker. Do they have these Ohio voters hooked up to some EEG to figure out their “+” or “-”? It doesn’t even say more or less of WHAT.
