I follow politics somewhat, but I have to admit that I'll vote straight-ticket in elections I don't know anything about. The reason being that election coverage of the small-town, local elections is terrible. When I lived in a big city, it was easy to grab a paper the weekend before elections and get a summary of where politicians stood on various issues. Not so in the small town I'm in now.
I vote in local elections only. I have never voted for a president even though there have been two opportunities in my lifetime.
As a subscriber to conspiracy theories, I haven't ever felt that presidential elections need my vote. And as the system is currently set up, they don't really. I feel that my local votes supplement the presidential vote.
I follow international politics more than I do politics at home. British politics are quite dull, as all the parties complete to be the most centrist. I already know who I'm going to vote for anyway, on ideological grounds.
American presidential debates always give me a good laugh, as both sides seem to compete to see who can be the most extreme in their position.
I try to follow politics as much as possible. It's a shame other people my age don't vote as much. If students were a larger voting block than funding for higher education sure as hell would not be getting cut as much as it is now!
