It's pretty early to be thinking these things... but I'm considering giving my vote in the 2006 Utah Senatorial Race to Pete Ashdown.
It's funny, I go to Pete's site from a link over at Ethan's blog, and take his little survey — which is mostly a tool for collecting contact information. No problem. So I get to the question of what issues matter most to me, and I jot down a few: privacy, intellectual property, national security, the patriot act, environment, and corporate welfare. Then I wander over to his issues page... and look what he has listed: copyright, economy, education, nuclear testing & weapons, privacy, patents & trademarks, and technology. It's a happy coincidence, sure... but one that piqued my interest.
More (I am certain) on this issue, in the months ahead.
