I love the concept! I would like to sign up, however, first I should add this disclaimer -
If I behave in a manner or express opinions (about my role as a voter/representative within the game, of course, not about any real-life issues) which mirror those of any RL politician, present or past, that won't be dubbed 'roleplaying', will it? Politics being politics, I think it's pretty much impossible that art won't imitate life to some degree here - if we don't point out the resemblence, I assume we're safe, right?
(I'm not talking about an outright caricature, such as mimicking the verbal idiosyncrasies of a real politician, for instance (would I do that?

), but similarities in strategy only.)
If that's ok, please sign me up!
