a week is a long time in politics

proverb Due to the fast-changing pace of the political landscape, the fortunes of a politician or political group can change drastically just in the course of a single week. The phrase is attributed to British Prime Minister Harold Wilson, c. 1964. The challenger is enjoying a surge in popularity after the debate, but there's still time before the election, and a week is a long time in politics. I'm exhausted by the amount of bombshell stories about the candidates that have come out this week. I know that a week is a long time in politics, but yikes. A: "Thank goodness this election is over in a week." B: "Don't get too excited—a week is a long time in politics after all."
