I read this just now, another article regarding the attempts to remove Proposition 8 from the ballot, primarily because it represents a "revision" to the Constitution, rather than an "amendment." Not an easy read, but a convincing case.
Money quote: "If the Supreme Court permits Proposition 8 to be placed on the ballot, the Court in fact would have harmed the very institution it sought to protect. If Justice Ronald George and the California Supreme Court fail to remove Proposition 8 and we win in November, our marriage rights may, NO RATHER WILL, be put up to a simple initiative vote at every major election cycle. Whoever loses will always return. And with that threat, same gender couples will face the continual threat of invalidity, without any of the permanence the framers envisioned for the California Constitution."
