The newest version of the Nebraska Voter Information Packet (the most complete survey on state candidates that you're going to find) is now up and online -- in plenty of time for you to do your homework prior to the May 13th Primary Election.
The VIP is a non-partisan effort offering information on legislative and citizen initiative issues as well as candidates' positions (in their own words) on these issues. There's no attempt to spin the data...just provide a lot of it.
