According to AP:
Forty-nine percent of people who identify themselves as Republicans don’t know what their party’s other common designation — GOP — stands for, according to a new Vanity Fair / CBS News poll.
The survey of 1,165 adults nationwide found that 51 percent of Republicans correctly knew GOP stands for “Grand Old Party.”
The next highest number, 34 percent, thought it meant “Government of the People.” Five percent said it was “Grumpy Old People” and 5 percent said they didn’t know. Four percent think it means “God’s Own Party” and 1 percent think it’s “Gauntlet of Power.”
