Well how can they have both elections in one night? How do they know who's going to win the primaries and advance on to the special election? How were Bilbray and Busby selected for the special election? This makes no sense to me.
They had a primary back in March - Busby won with 43%, Bilbray had 11% but beat out the other Republican candidates. The top vote getters in each party advanced to the runoff today. The reunoff is to fill Cunningham's seat through 2006.
The primary today is for the 2007-8 term - Bilbray and Busby are winning handily. We'll have a rerun in november.
