I do not think either Iowa or Vermont will affect the decision in California. Remember, the California court already did what the Iowa court did, so it is on the same page. What the California court now faces is really a different issue -- can a majority vote rescind a Constitutional right?
Vermont only makes it easier for the Court to validate Prop 8 on the theory that the Legislature could override it if it wants to -- which of course, the legislature did as a statutory measure, but for an amendment to the Constitution requires a much more difficult process.
