I spotted this on the blog site LA Observed (laobserved.com):

Check out this story about Gil Cedillo in the Capitol Weekly.

Cedillo, who is known for supporting drivers licenses for illegal immigrants, tried for the San Gabriel Valley House of Representatives seat won by Judy Chu. But he was trounced by Chu, who had much stronger local connections.

Here are the results for May’s Democratic primary:
JUDY CHU DEM 17,668 32.63
GIL CEDILLO DEM 12,577 23.23

He looks like he is going to take a run at an assembly seat in Los Angeles.
