pres impersonators opening.jpgElection day approaches, and the results could have a life-changing effect on a certain segment of the population. No, not immigrants, millionaires, women, small-business owners or the rest. The people who really feel an immediate effect after each election are the presidential impersonators.

Think about it: When Jason Sudeikis re-upped with "Saturday Night Live," didn't you suspect it was because the show was hedging its bets and keeping its best Mitt Romney on staff?

So as you watch the debates and decide who to support at the ballot box, take a look at these once -- and possibly future -- presidential impersonators
