Drain the Swamp Was Once Literal Public Health
To drain is to draw liquid away. The phrase about draining a swamp began as real malaria control before it became political.
To drain is to draw liquid away, or to exhaust something gradually. *Drain the swamp* started as literal public health policy: standing water breeds mosquitoes, so draining marshland was the standard way of fighting malaria from Roman times to the twentieth century. Only later did the phrase become a metaphor for clearing out corruption. *Brain drain*, the loss of skilled people from a country, was coined by the Royal Society in the 1960s.
