The Los Angeles Times has online resources for following the money race to pass or defeat Proposition 8, California's anti-gay marriage amendment.
There is an interactive map that allows the reader to click on a county to see how much money came from that county and by what margin that county voted against 2000's Proposition 22, the Knight Initiative. Proposition 22 barred same-sex marriage by statute and was approved statewide by 61.4-38.6.
Click on the green bar to find figures for marriage ban opponents, and on the blue bar for marriage ban supporters.
As of yesterday, gay marriage supporters have raised $5,702,253 versus $3,500,090 for opponents.
There is also a donor database that can search by city, ZIP code, or state (use two-letter postal abbreviations). Find out what the neighbors are up to.
