How can they do this?
Isn’t it up to the party to decide how it is done and if you don’t like it you form a new party?
It’s too hard to form a new party. In Illinois, republican, democrat, and green party statewide candidates must submit at least 5,000 petition signatures, to ensure that their names will be on the ballot. Candidates of other parties must submit at least 25,000 signatures. The major parties want to ensure that no one else can oppose them.
