What Will It Take To Defeat Prop 8?

I've been trying to figure out what exactly needs to happen today to defeat Prop 8. Do we need to have a 2/3 majority? A simple majority? It turns out that all either side needs is a simple majority.

What is a "simple majority?" It's exactly what it sounds like -- it's a voting requirement of more than 50% of all ballots cast. [Wikipedia]

This is why every vote counts. Since the California Supreme Court ruling, more than 18,000 gay and lesbian couples have gotten married in California.
