I used to think the same, then I realized something very essential to starting out with a reasonable, realistic Election Turnout %.
For example, in Freedonia, Liberal and Atheist, the default party you get is the Liberal Party, or something, and if you choose this party, you would start with ~35%-~40% to start with, whereas if you choose the National Front Party in Freedonia, you would start with an incredibly low Election Turnout %.
Theoretically, you should select a Party that coincides with the original politics of your country, and/or, if the politics of the country you selected doesn’t coincide with your personal politics, which therefore means that the people you would try to attract (patriots, socialists etc.) go against your personal principles, simply select a different country!
Choosing The National Front in Freedonia or The Freedom Party in a Military State will always give you a big challenge, like for example, in real-life, choosing to represent the Communist Party in the USA!
Nevertheless, it will always be unrealistic if you do get elected as a Communist Representative in the USA… but hey, it’s a game! Otherwise it wouldn’t work, would it?
