"Saturday Night Live" has always been a default place to find political impersonations. The show has been doing them since the '70s, and is probably already prepping the impressions they'll need to have ready for the next presidential election. However, political impersonations have always been found everywhere in American culture -- some people pick a politician and make being them their job, others unveil impersonations at the dinner table. If you're in politics, making fun of your colleagues is almost a requirement. For celebrities, having a Bill Clinton impression at the ready almost seems a requirement nowadays.
