For a slightly different take on it, Suzerain was great.
You manage a government from election to power, but its all done via text conversations. You have to make choices and compromises to get where you want, and plenty of things come back to haunt you later. There are Communist Soviet/Capitalist American analogues that you have to negotiate with as a smaller world power.
As President Rayne, lead the nation of Sordland in your first term of this text-based RPG. Navigate a political drama driven by conversations with your cabinet members. With looming war, rooted corruption, economic crisis and reform needed, the choices fall on your shoulders. How will you lead?

I really enjoyed it, it manages to humanize politicians in a way. Will you compromise your morals if it serves what you believe is the greater good?
Maybe not excactly what you're looking for but its in the ball park if you're talking about choosing between socialist and capitalist economic policies and conservative/liberal social policies and how that might turn out.
