This week Lindsey Graham’s sister-turned senator appointed as his replacement finally took questions from South Carolina voters.
The Internet rendered its verdict after Graham committed an unforced error of epic proportions.
What she spouted about the people of the Palmetto State in one debate response left Republicans slack-jawed.
Graham Told Voters South Carolina Has Fifty Million People
Darline Graham was asked a simple question about the affordability crisis in her state.
She answered with a number nearly ten times the size of reality.
South Carolina has about 5.5 million people.
Graham told the debate audience it has 50 million.
That is more people than the entire state of California.
It is more than twice the population of New York state.
Ralph Norman was the first to respond, posting his own tweet within the hour checking Graham's number against the real one.
He got in a dig at her for lecturing voters about affordability while getting the state's basic size wrong by nearly ten times.
State Rep. Adam Morgan piled on a couple hours later.
"She thinks 50 million people live in South Carolina?" Morgan wrote. "Are we being punked?"
By Wednesday morning Morgan's post alone had pulled in more than 22,000 views and dozens of replies from South Carolina Republicans who could not believe what they had just watched.

National Security Is Not My Thing Was Not a Joke
The population blunder was not Graham's only bad moment on that stage.
A moderator asked her a straightforward question about Taiwan and the South China Sea.
Graham told the room national security is "not my thing" and "not my area of expertise."
She pivoted instead to her brother's 33 years in the Air Force and her father's Army service, as if a family member's uniform could stand in for her own homework.
Nikki Haley was not having it.
"National security is not something you inherit," Haley posted afterward. "It's critical in the U.S. Senate."
That line landed because it named the exact problem South Carolina conservatives have been whispering about since McMaster made the appointment.
Rep. Nancy Mace piled on too, mocking Graham's grip on basic facts about the state she wants to represent for six more years.
Two unforced errors in one debate is not bad luck.
It is a pattern.
Why South Carolina Republicans Keep Picking Outsiders Over Heirs
Haley and Mace did not pile on by accident.
Both of them know South Carolina voters are still forming their first impression of a senator nobody elected.
A stumble like this one sticks precisely because it confirms what conservatives already suspected about how she got the job.
It plays right into the case Ralph Norman is making.
Darline Graham has never won a single vote for this seat.
She got it from a phone call, not from South Carolina voters.
South Carolina conservatives built a movement over the last decade around outsiders who show up prepared, run the numbers, and earn every vote instead of inheriting a nameplate.
A senator who cannot name her own state's population, then shrugs off national security as somebody else's job, is not the outsider that movement fought for.
She is the exact insider class it was built to replace.
Voters do not need a poll to tell them which candidate did his homework and which one improvised in front of a live microphone.
They just watched it happen.
