When I check the race box as Caucasian, does that also mean I’m a Russian?
Caucus mountains are in Russia.
So they need to be vigilant in barring not only Russians, but also Georgians, Circassians, Ossetians, Chechens and Azeris.
The "no Georgians" rule might have been a good idea for the Presidency at the time of the 1976 election.
