I can assure you, you're not alone. I too condemn those who shirk their electoral responsibilities. But I believe that those responsibilities come with more than just going in a booth and voting... but with being informed and making your mind up based on experience and hearing a multitude of view points in the time prior to the election day. I do not condemn those who have no interest in the electoral process of debating and discussions and and then don't go to vote. I do condemn those who do follow the public discussions and then don't go and vote. And I also condemn the reasons as to why people choose not to follow notions of public interest.
So there are a great deal of nuances in that regard.
However, the crappiest american, and in fact, the crappiest voter, regardless of what republic he is in, is the single issue voter. The one who cares only about one thing, and the candidate who promises him that, he will get his vote. The reason why I consider this breed of voter to be the crappiest is because he is often focused on issues that should occupy, at best, a secondary or tertiary role in the public life of a country... and usually has a very straightforward approach to it. Notions like the economy and how it should recover, corruption, laws that were approved and their effects and other such complex issues that usually have more than 1 side to them are alien to the single issue voter. He instead sees issues like marijuana (not the war on drugs, just a small, simple part of it), gay marriage, guns (not the entire issue about guns, but just his own little preferences) and other such notions as the key issues of the day and makes up his mind according to that.
he is the voter who is most easily swayed by the politicians who have to smile and be convincing when they promise something and is one of the many reasons why democracy is going down the drain. He is the crappiest voter.
