You read the exact opposite of the meaning there. There are more positions in government than people willing to run for them period. There are more funded candidates that get a salary from their political party to hold an office, but the vast majority of elected government positions are held by people without a party, because quite frankly political parties are stupid, worthless, and inherently anti democratic.

I’m sorry you hate local government, and I’m sorry you’re ignorant about how politics work outside the pointless sideshow that happens every four years, but that does not mean the greens don’t have a proven track record of getting into office.
