The presence of the Mississippi Freedom Democratic Party at the convention in Atlantic City, New Jersey, was inconvenient for national leaders. Democratic Party organizers had planned a triumphant celebration of the Johnson Administration's achievements in civil rights, rather than a fight over racism within the party. Johnson was also worried about inroads that Republican candidate Barry Goldwater was making in what had been the Democratic stronghold of the "Solid South", as well as the support which Independent candidate George Wallace had gained in the North during the Democratic primaries. The all-white delegations from other Southern states threatened to walk out if the official slate from Mississippi was not seated.
