Americans are learning that a rotten apple can ruin the bunch. A bad individual among many good ones, and especially one will spoils the group.
This expression is a shortening of the proverb a rotten apple spoils the barrel, coming from a 14th-century Latin proverb translated as "The rotten apple injures its neighbors." The allusion in this idiom is to the spread of mold or other diseases from one apple to the rest. In English, the first recorded use was in Benjamin Franklin's Poor Richard's Almanack back in 1736.
And it still applies today in politics as in one person whose own words and actions negatively impact an entire group of people, a nation and everywhere, including the high seas. This was no love boat, but a hated cruise from hell.
