How much of what's portrayed on shows like "House of Cards" and "Scandal" actually happens in government? | My exgf father hates the show he says its so unrealistic and nobody talks like that.

If we all feel lobbyists make America corrupt, why can't we simply vote to ban lobbyists on election day? | Your premise is wrong; people *love* lobbyists!
