The SF Chronicle has the link on their website to search the public-record database of where the funding both for and against Prop 8 has come from:
If you select "CA" for state, it will then allow you to select "Pleasanton" for city. Check it out. I find it *very* interesting the number of very high donations FOR Prop 8 from folks here in Pleasanton -- $25,000 donations, many $10,000 donations, etc. The donations AGAINST Prop 8 are more what you'd expect from individuals -- $25, $50, $100.
This makes me wonder two things: 1) Are these very large donations FOR Prop 8 really from individuals, or has a church funneled money from a general fund through these donors? and 2) Has a church (or churches) told their members that if they donate large sums of money, this would be considered their "tithe" for the year (or subsequent years)?
