Michelle Obama: 'If we ...play around with a protest vote, Hillary's opponent wins. Period."

Appearing at a star-studded Hillary Clinton rally in Philadelphia, Michelle Obama was the biggest star of all, encouraging the crowd and national television audience to get out and vote for Hillary Clinton on Tuesday.

"Standing here tonight is perhaps the last & most important thing I can do for my country as first lady," before adding, "If we stay home or play around with a protest vote, Hillary's opponent wins. Period."

The current First Lady was introduced by former President Bill Clinton as, "The finest surrogate ... any candidate for president has ever known."
