From what I have read, if someone votes "NO" on the recall, they do not get to vote for a replacement. Or if they do, the ballot is void. So this would mean that a Davis supporter would have to choose between Davis and Bustamante. If Davis gets about 20-30% "NO" votes as expected, that would mean that Bustamante gets 10-30%.
Wrong. Voters vote on both.
Now, get back to your fares.
Every voter gets to vote on both parts of the recall ballot. Only if Davis is removed by a majority voting against him on the first question, does the second question, who should replace him?, come into play and get officially counted.
The logic of this is clear. No voter knows, as he/she steps into the voting booth, what the outcome is going to be on recalling Davis. Therefore, each one gets the opportunity to make his/her choice known on replacement -- pending the final count and the decision on Davis.
