Of course Thurmond should stay  I had assumed he wasn't in the BAN list because his party claimed to be the Democratic Party (and in many states was), but it does appear he was not on the ballot in enough states to have been able to win.  He and his party are obviously a special case, with strong appeal and organization only in a narrow region.  I think including all those who were on enough ballots, or received at least 0.1% of the total popular vote, or carried at least one state would work well. - Talk/Cont
