for both the Dem and Rep primaries - about 30% of registered voters. A much higher turnout was expected. I believe that that's why the polls were screwed up. The two races were somewhat similar - a known name with money, and backing from the party bigwigs, against a less well known competitor with less money, but with more support from their hard core bases - progressive (Mike Miles) or conservative (Bob Schaffer). Those were the only significant races. The only other question I had to vote on was for the CU Regent, and one of the 2 candidates had pulled out of the race - of course I, and many others, voted for him and he won with over 60%.
The big difference for November is that, compared to Coors, Ken Salazar actually knows what he's doing. He's been the state AG for years (i.e. he's won statewide elections before) and remains popular because he's a moderate dem. And besides, his wife owns a Dairy Queen.
The best line from the primary debates was from Mike Miles - The only thing Pete Coors has going for him is a lot of money and bad beer.
The voting machines in my county (Broomfield) were just for counting. We filled in large ovals with a felt pen. The ballot was card stock weight, not paper. You then put the ballot into the machine which counts and saves the ballots. I don't know if it would tell you if it was filled out wrong - eg voted for 2 candidates. The Dem and Rep county chairs checked the machines out together before the election and were satisfied that they counted as well or better than they could by hand. In any event the hard copies are saved for recounts. I am generally suspicious, but these seem pretty good.
