Continuity mistake: When we first see Tara, as well as in the shot where Scarlett is running away from the Tarleton Twins to meet her father returning from Twelve Oaks, there is a very large tree directly in front of the main house. There are two white peacocks underneath it. In all subsequent shots of the house, when Scarlett and her father are talking in the sunset and again when her mother is arriving from taking care of the poor white trash Slattery family, the tree is completely gone.
Visible crew/equipment: When Mammy catches Scarlett trying on a pretty bonnet when she is supposed to be in mourning, when the camera pans wide to show the room, in the mirror on the wall behind Scarlett you can see the shadow of the grip holding the mic above Scarlett.
Revealing mistake: After Frank Kennedy's death, Scarlett is drinking in her bedroom, when she spies Rhett arriving outside her window. She then races to the mirror to brush her hair. She does not actually touch her hair with the brush strokes, probably so as not to disturb her hair, which had been specially styled by hair and makeup staff.
Answer: To answer your question, I looked for on-line versions of the "Gone with the Wind" screenplay. What you are hearing as "other 48 states" is actually "those fool Yankees." The full line is, "Y'know, those fool Yankees actually want a war?" Also, the line is actually said by Stuart Tarleton, played Fred Crane, not by George Reeves as his twin brother, Drew. In writing, it doesn't seem they would sound alike. When I watched the opening scene of "gwtw" on YouTube (https://www.youtube.com/watch?v=ymbmvQJcLDc&t=6s), I can see how the error was made. I might have misheard it, as well, if I didn't already know what the line was from my research. Mr. Crane's enunciation is rather muddled.

George Reeve plays Brent Tarleton, not "Drew."
