Ultimately, the decentralized structure of the RNC created numerous pitfalls for an aspiring national candidate. The RNC occupied the most public position in the Republican hierarchy, but contemporary observers and scholars regarded it as the weakest organization in the party structure. The major sources of policy-making and party direction were publicly elected officials, whether the President, the members of the Congressional and Senate Policy Committees, or the state parties. Power either flowed downward from the White House, or upward from the several states, into the national committees, which were generally prevented from taking a clear stand on an issue or moving in a certain direction due to their diverse and self-interested memberships. The lack of a clear authority, the need to keep the party broad and inclusive, and the competition among potential presidential candidates routinely prevented RNC chairmen from emerging as the most prominent voice of the party.32 When the Republicans were out of power, as was the case from 1932 through 1952, the RNC took on more institutional importance. As the formal head of the party's most public governing body, the chairman had regular access to the national press. Since he did not hold elective office, his relationship with the opposition party did not impact his political future. Because the position was national in scope, large interest groups that generally supported the party worked through the national committees to advance their own agendas.
