While there are a LOT of problems with the Belgian political system (its only saving grace being that our whole country is smaller than LA so who cares how we run it?), at least the voting bit is better-organized to ensure maximum participation.
1. Voting day is a national holiday and NO-ONE can be prevented by employers from going to vote (polling places are open long enough that even those with jobs that need 24/7 staffing can have a shift switch and some can vote before, some after work)
2. Voting is a duty, not a right - you have to supply a reason not to vote (doctor's note, travel documents, whatever) and even so you can give someone else authorization to vote on your behalf)
3. Every citizen is automatically registered to vote and given a free voting ID
4. At least one voting spot per 2000 people and within max 2 kilometers of every voter; where this isn't feasible, free transportation to your nearest voting place; also transportation available for those who can't drive/walk/bike/get there themselves if they desire
About 85% of people of voting age vote; the majority of those who don't are either 80+ (nobody bothers to give a fine to the elderly in nursing homes and stuff...Though in some cities they just put a voting booth in the nursing home to make it easier for them) or are anti-system (and, well, fair enough I guess).
Sure, about 5% choose to cast an invalid or blank vote - that's also absolutely a right. But getting 80+% participation feels a heck of a lot more democratic than whatever it is those guys in your South do. Of course, this'll never happen in the US because of half a dozen reasons, most importantly that the Republicans wouldn't ever be able to win nationally. But, you know.
