One way to turn off people is to be seen gaming a system. That's what is happening in California where two Democratic candidates for governor are boosting Republican rivals in an effort to knock each other out of the two top spots in the primary election. Why? California has a primary system in which the two top vote-getters regardless of party go on to the general election. The Democratic candidates know that running against each other will be difficult in the general election because the state is sure to elect a Democratic governor. It will be much easier if the opponent is a Republican. So, they are running ads supporting Republican candidates in the primary. It is a cynical move but legal. One can easily pardon voters if they don't like either Democratic candidate as a result of their gaming the system. It would be ironic, if as a result of their chicanery, the two top winners are Republicans.
