I am surprised the people have 100% happiness, they aren´t worried about frequent assassination attempts, and they aren´t worried about countless congresspersons being robbed, I guess....
No, Invoke Military service is a normal advanced ability, strong on some, normal on some, weak on some, gaffe on some bills. Without your trait, you wouldn´t have access to it.
If your constitutents are completely confident, you have reached the maximum. Any damaging action(voting out of lines, acting on poisoned bill) will decrease it to very confident. It is a waste of money to do ads when your support is that high.
The game is mostly exempt from copyright on that topic due to a couple things: first and foremost, the game is satire. That alone is a valid defense against copyright claims. Second: copyright rarely applies to something like a fictional name. It DOES apply to something like a character which LOOKS like superman, though. That's why City of Heroes had issues and had to restrict people from creating likenesses of popular superheros (also consider that City of Heroes is not satire -- you're playing a superhero in as realistic of a way as possible). Finally, since they're now player submissions it gets a lot more difficult to claim I'm trying to do it to make money off of their success.
