Ford is forgetting that replacing 15 councillors is very, very, very unlikely even if he were enjoying stratospheric levels of popularity, which he isn't. Ward races are essentially local and all about name recognition, and if people remember your name in the voting booth, and don't really remember anything bad about you, you're in. If you're unpopular, but your opposition is hopelessly split, you're in. If all you did last term was essentially do nothing, you've got a good shot at re-election. If you're not hiring a bunny suit with taxpayer money, you're fairly safe. It is extremely hard to unseat a do-nothing councillor, and even harder to shift one halfway competent but with flaws. Not many people are *that* interested in non-Ford municipal politics. Changing the system to ranked ballots will help, but the returning councillors always vastly outnumber the new faces after each city election.
But then he's forgotten a lot of stuff. Are you perfect? Any questions? We're moving on.
