That’s covered in the rather lengthy article. Most of the Brits’ effort was concentrated on defeating isolationists such as Hamilton Fish. They came close in ‘40, got him redistricted and defeated in ‘44.
I don’t see any mention of them involving themselves in redistricting in the article
A)Not cool!
B)I want to see THAT James Bond movie
What the deal with that 1944 race, DJ, new districts, Fish lost to a fellow Republican, who failed to beat him in the primary but won in November on the rat line and was himself defeated in the primary in ‘46?
