Well, there is a supremely good (and supremely old) presidente simulator called
Hidden Agenda. It's basically free now, if you really want to play it straight you can visit the author's site (wikipedia, bottom) and donate a few pfennings to his cause(s).
In essence, it's Tropico before Tropico, but when shit get's real. Like, get real really fast, really hard. You will loose, no matter how good you are, and basically a rule of thumb victory is if you don't get killed or deported before your four year office run is over. I'm just saying here, if you want to be humiliated and need an ego hit, play this game at least once to experience the full force of "damn ungrateful lemmings".
