For Conservatives to win, only a widespread Energy Scarcity can help. Energy scarcity leads to inability to run an urbanized globalized world. After energy is scarce each person needs to go back to having 10 kids each to use as free labor in their own farm land. Women will spent an entire life time raising their 10 kids, and as a result they will become financially dependent on men. People will get married early as life expectancy fall. There will be no time for promiscuity, or alternate sexual lifestyles. And the old morality will take over again.
