On March 6, the San Jose Mercury-News carried this story, asking if California is likely to change its top-two system to something else.
The story erroneously says California had a closed primary before top-two started in 2011. This is not true. For 2002, 2004, 2006, and 2008, California had a semi-closed primary for congress and partisan state office. In all those elections, both the Republican Party and the Democratic Party let independent voters vote in its non-presidential primaries.
