If encouraging voting is electioneering then surely withholding information about voting is as well.
And if "go vote" is a threat to democracy then I shudder to think of what newspaper endorsements, superpac advertisements and opinion news channels are. Heck, election day isn't a federal holiday so flexible work hours (which favor the professional class and therefore Republicans) must be a conspiracy to sway elections!
It's baffling that anybody takes this seriously.
