Unpledged electors were on the ballot in Louisiana, Mississippi, and South Carolina.
Andrews wasn't on the ballot in any of those states though.
ok. then who were they for? Who got the Popular votes pledged to the Unpledged Electors?
Now I see your question. Nobody received the popular votes. The votes were cast for the slate of electors who were not pledged to any candidate (hence unpledged electors) as opposed to being cast for a slate of electors pledged to Stevenson or a slate pledged to Eisenhower.
ok. but how did the people in the Southern state know they could vote for Unpledged Electors? The vote was high in some of the states. So, I guess someone got the word out that that's what u could do for that election.
There was an entire unpledged elector movement going on in the South following the 1948 Democratic convention and the Dixiecrat "insurgency". Many of the people involved were regular southern Democrats who knew they had to remain loyal to the national Democratic party but wanted to keep their options open with regard to supporting the presidential nominee. The Unpledged Elector movement allowed them a way to be Democrats (and keep their congressional seniority) while making certain that any nominee considered too liberal or too pro-civil rights would have to face the prospect of the "Solid South" not being so solid.
