Religious Voters
I have found that a successful tactic to win elections is to increase the amount of the population that is religious by teaching creationism only and installing twice a day prays. Even without using faith schools subsidies the percentage of the population that is religious rises and they become fanatically supportive. Neither of teaching creationism or school prays cost any money and therefor they are a very cheap demographic tom please as long as you oppose anything that would upset them. I have ended up with over 90% religious and they have really helped me get through the elections.
Poor Voters
I have found that reducing poverty harms the chances of re-election. This is because it reduces the number of poor voters who are supportive as long is there is some welfare provision. And instead they become middle income who are very hard to please.
Smokers, motorists and drinkers
I have a dilemma with these voters as they bring in huge amounts of tax revenues but are hard to please and often oppose my government. I managed to eradicate smokers which prevented opposing votes but reduces income.
What tactics do you have to change the percentage of demographics?
And what are the advantages and disadvantages of it?
