On this primary election day. the headlines may be about the vote count but the real story will be in the delegate count, particularly on the Democratic side.
The formulas are confusing, but here's one clear fact: The two congressional districts that include parts of Ventura County are among the 21 in the state in which Hillary Clinton or Barack Obama have an opportunity to separate themselves from the other. The reason: Those two districts, the 23rd and the 24th, will each send 5 delegates to the national convention.
Each district is assigned from between 3 and 6 delegates, based on the number of Democratic votes cast four years ago. In the 32 districts with even-numbered delegates, one candidate would have to win more than 58 percent of the vote to gain an edge. Otherwise, each candidate will receive the same number of delegates.
In the odd-numbered districts, however, the candidate with the most votes will get an extra delegate -- for instance, if Clinton were to beat Obama by just one vote in the 24th District, she would get 3 delegates and he would get 2.
For hard-core political junkies, the odd-numbered districts are the ones to watch tonight. For a complete list, check the California Democratic Party website.
