You’ve probably used the idiom before; you want to “keep the ball rolling”. The phrase, if you aren’t familiar, means to keep up a situation or activity, to keep it going.
The source of this phrase is early. It starts with an eccentric man named Jeremy Bentham, who wrote to George Wilson in 1781 to try and keep a conversation going. He wrote, “I put a word in now and then to keep the ball up.” (“Keep the ball up” was an older, British version.)
But the guy who really established the phrase was none other than Benjamin Harrison in his 1888 presidential campaign. His supporters created a giant ball covered with campaign slogans and rolled it from campaign to campaign across the country, chanting “keep the ball rolling”. They rolled the ball about 5,000 miles, across many states, to Indiana, Harrison’s home state.
Don’t you hear from every quarter, quarter, quarter / Good news and true, / That swift the ball is rolling on / For Tippecanoe and Tyler Too.
Harrison’s campaign was the first with a political slogan (“For Tippecanoe and Tyler Too”). Harrison’s campaign against Grover Cleveland was a close one, but Harrison won in the end.
