Worse still, democracy relies on informed citizens.
No it doesn't. This is literally the oldest anti-democracy argument; people are too stupid to rule themselves.
Citizens are entitled to vote because they're subject to the authority of the State. Dumb people still have to pay taxes and obey the police. A voter who chooses a candidate because Mars is in retrograde casts a ballot that is every bit as legitimate as the head of the political science department. "low information voter" is an argument for voterID, poll taxes, and literacy tests; it's voter suppression.
