From the video:

If you want long years in office, the rule of three is your friend in a democracy as much as in a dictatorship. You can’t eliminate those who don’t vote for you, but there’s a lot you can do. Once you are in power, make it easier for your key blocs to vote and harder for others. Create voting systems that reduce the number of blocks you need to win as many rivals as possible. Set election boundaries to predetermine the outcome for you and your friends. And make party defaults with byzantine rules to determine which blocks even can vote for. Combine and mix the above methods for an even more pronounced extension of power. When the satisfaction rate cannot be lower, but the re-election rate cannot be higher,you’ll know you’ve made it.
