"Did Not Vote" won 11 of the 12 last U.S. Presidential Elections

It doesn't, really. It just needs to be easier to vote, and for a longer period of time. Here in Sweden it's not a national holiday, but you can vote up to like a month in advance all over the place and it takes like 5 minutes if you do that. You can stop by on your way home from work or to the grocery store no problem, or on your lunch break. If you go on election day it might take you up to 30 minutes if there's a line.
