Famous ‘Oops’ Moments of Campaigns Past

On this Super Tuesday and Texas primary election day, we recall some of the worst mistakes politicians have made while running for high profile offices.

Many political campaigns make missteps on their way to primary or general elections. In recent days, the Ted Cruz campaign pulled a campaign ad which happened to feature an actress who had appeared in soft-core pornography. And Marco Rubio's campaign unveiled an ad referencing Ronald Reagan's "Morning in America" ad, citing it was "morning again in America" – but the ad featured stock footage of Vancouver, British Columbia, and a tugboat bearing a Canadian flag.

These sorts of "oops" moments occur all the time. But what are the most famous oops moments, gaffes — and even some dirty tricks we've seen in elections?
