Rich supported a ballot initiative in California called "Proposition 90" which prohibited cities from "using their condemnation powers to transfer property from one owner to the other." It generated significant controversy. Property rights referendums on 12 state ballots became the "biggest ballot issue" in 2006. By September 2006, Rich gave to advocate "yes" on Proposition 90, dubbed by proponents as the "Protect Our Homes Act", while various opponents gave to advocate against it. A second estimate was that Rich gave via the Fund for Democracy and Americans for Limited Government to foster advocacy of eminent domain initiatives in California, Nevada, Arizona, Washington, Idaho and Montana. Another estimate was that by November 2006, Rich spent promoting state initiatives.
