The poll doesn't include the best political game of all:
I don't know how
realistic it was, but I really enjoyed Tropico. I'm sure you can find a demo out there on the internet somewhere. You might have a bit of trouble getting the original to work on a modern PC, though. It came out in
2001. I found a copy on ebay for about 3 or 4 dollars, after I sold my original at a yard sale (regrettably), and I managed to get it working on Windows 7 but I can't remember what I did to get it working.
Back before I found out about Ron Paul, I played original Tropico and would try to see just how tyrannical I could be on the hardest difficulty setting without getting booted from power. The U.S. would always send troops before the people even revolted. (and if either the U.S. or USSR invaded it was instant game-over for your regime, just like in real life). You could build an embassy to increase relations with the superpowers and keep them off your back . . . for a while, at least.
You could have elections and try to please enough people to win, or you could cancel elections and face a possible uprising from your people. Of course, if you created a leader who starts out with low democratic expectations (you can create your own dictator at the start and pick your characteristics), then the people won't be all that upset if you cancel the elections (which usually don't happen anyway, lol.)
There were various factions you had to try to keep happy. You could build schools to please the 'intellectuals', but they were typically the ones who demanded better pay, jobs, and housing. The 'religious' faction wanted churches and policies like alcohol bans, which was costly because churches weren't cheap and rum was one of the most-profitable goods you could produce and export, but the religious faction was usually one of the largest factions so you had to throw them a bone one way or another.
I bought tropico 3 but found it a bit too easy. Now they've just released Tropico 5, so I'm a bit behind. I prefer the original, though. The original was created by Pop-Top, the game developer who also created the Railroad Tycoon series, which had a really fun use of the stock-market to try to buy up shares and buy out competing railroads.
