It tells you that politicians are only ever in the game to win elections, and, in that moment, just before the election, this was the way to approach the hearing that seemed most tactically appropriate to both sides. That's not actually something I want to know; we've already known that that's how politicians behave for centuries. I'd be a lot more interested to know if social media is influencing the public political discussion in meaningful ways, and how, and to what end. But those questions were never going to be answered in any sort of compelling way by a gaggle of politicians trying to score cheap points in front of their constituents.
