Once of the dangers of competition has always been that the winner is often in position change the rules. It appears liberals in California have successfully changed the voter laws such that in some districts there will be no Republican Candidate on the ballot.
At least five Districts surrounding San Francisco will have no Republican candidate, two Democrats will compete in the general election in each district. Since Proposition 14 passed in 2010, Californians can vote on only the top two candidates from the primaries even if they are from the same party.
This was billed as a way to force politicians to move toward the center and appeal to a broader range of voters. In reality this is major bias in favor of the majority party.
In the case of the Bay area, four Republican candidates faced off in the primary election, dividing the votes, but together they garnered more votes than the number two Democratic Candidate. In other words the Republican Party will not be represented in the general election even though their selected candidate represents the votes of the entire party.
Proposition 14 is now the law in California, unlike Proposition 8 which was passed by a majority of Californians prohibiting same sex marriage and was then thrown out by severely biased judges. More recently a set of 9th Circuit judges re-defined the 2nd Amendment. California seems to have lost its way with regard to democracy and American values.
This policy eviscerates the American traditional two party system, and ensures the Republicans and conservative values do not get the exposure in the general election that allows balance in American politics. This is underhanded by any standard.
