Riley J. Wilson – Four intervening years had made Louisiana 's political and economic establishment begin to see Long as a threat . Consisting of wealthy planters , businessmen , and New Orleans 's Regular Democratic Organization political bosses , the political leadership of the state united behind the candidacy of U.S. Congressman Riley J. Wilson of Ruston in July 1927 . His campaign focused on the threat of Long 's radicalism ; a banner reading " It Wo n’t Be Long Now " was featured prominently at Wilson 's campaign stops . Wilson 's reputation was tainted by his connection to what was perceived to be an inadequate federal response to the Great Mississippi Flood of 1927 ; he was the ranking member of Congress 's Flood Control Committee
