There’s something a bit gross about those ostensibly on the liberal end of things arguing for more government secrecy, as if we shouldn’t be allowed to judge for ourselves that what Republicans have put together is a trashy partisan attack. If that’s the case, it should be apparent from reading the thing itself; we don’t need the Democrats to protect us from politicking.
However, that’s also why the underlying intelligence is so important. Without it, we’re just taking the GOP’s word regarding what the memo argues or Democrats’ word that those arguments are bunk. The whole thing will devolve into a partisan poo-flinging contest that, I’d wager, even people with a more-than-casual interest in politics will quickly tune out.
