One of the interesting things about democracy is that we all want it, but we don't agree on what it is. This isn't simply a matter of disagreeing about the ideal election system while acknowledging that all of the variants are essentially democratic. Instead, the most common disputes over the conduct of elections turn out to be power plays as various factions try to change the rules in their own favor. Today it's the manufactured hysteria over voter-fraud, yesterday it was a battle over gerrymandered districts, and then there's the incessant jiggering of the rules over payments for political communications.
It's bad enough that politicians are constantly campaigning for re-election, but it seems that even when they are passing legislation, they're just thinking of how they can retain power. When do they find the time to actually do the people's business? My impression is that they don't.
