But the problem with the analogy is that Mueller effectively foreclosed any chance of the Democrats finding investigative gold. While the GOP could claim that the State Department’s internal investigative into Benghazi couldn’t be considered objective or conclusive, Mueller’s deep dive into anything remotely related to the Trump campaign and Russia yielded nothing proving collusion, and he refrained from pushing a dubious obstruction of justice charge against the president.

If Democrats could mock Republicans for obsessing about Benghazi, how much more could Trump and the GOP say if Democrats spend the next year seeking what Mueller’s comprehensive probe said didn’t exist?

The Benghazi probes may have chipped away at Clinton’s image, although they paled in comparison to the problems she caused herself with a self-inflicted wound over her emails and her cavalier attitude toward security. But there’s little the Democrats could find out about Trump that both supporters and critics don’t already know.
