I won't quibble with any of your numbers. Nevertheless, Arnold measures should have passed, but the voters that chose to cast their ballots chose otherwise. The only relevant facts are that the election is over, the Public Unions are in possession of the Key to the Treasury, and California is worse-off for it.
That is NOT a stretch!
The boring statistical parade was offered to emphasize that the quality of the candidate has everything to do with the level of participation in a democracy. If a candidate or candidates motivate allegiance and excitement, the level of participation will rise. In November 2005, the candidate motivated about 35% of the eligible voters. The result was that about 20% of the voting age populous was allowed to speak for the other 80%.
Personally, I prefer the Brasilian system from the 1960s. On election day, the military visited each household and escorted the eligible voters to the polls. Neighborhood by neighborhood participated in democracy as the day progressed. The military didn't attempt to influence the individual voter, they simply ensured participation. Even Amerigomag, holding only a permanent visa, was escorted to the polls to determine if he was eligible to vote.
