Following a two-week vacation in British Columbia after the primary, Nixon returned to the 12th district. The Republican began the general election campaign by replacing Roy Day with South Pasadena engineer Harrison McCall as campaign manager. As Chotiner was increasingly distracted by his position as Southern California campaign manager for the (successful) reelection bid of Republican Senator William Knowland, the Nixon campaign added publicist William Arnold.[39] Voorhis, on the other hand, remained in Washington, dealing with Congressional business and generating little publicity.
