Nelson Gross resigned his position as party chairman on April 9 to enter the race for Senate with the full-backing of Governor William T. Cahill. Cahill's support discouraged any serious contenders from challenging Gross in the primary.
Gross was nonetheless privately criticized as a poor choice by some Republicans due to his ongoing investigation by the United States Department of Justice for involvement with a Mafia-backed labor union. The investigation was led by U.S. Attorney Frederick Bernard Lacey, who had been personally recommended to the Nixon administration by Senator Clifford Case. Case and Gross had been on uneven terms since Gross undermined Case's "favorite son" status at the 1968 Republican National Convention by bringing Bergen County delegates into the Nixon column.

Gross assailed Williams as a "radical liberal" and implied that he was involved in "influence peddling" for having sponsored special bills for about 70 Chinese seamen who jumped ship in the United States.
Williams declined numerous calls for debates.

In our opinion, the case for the re‐election of Senator Williams is clear and persuasive... Senator Williams is far and away the better choice.
