Crosby in the Republican primaries after the Nebraska Republican Pre-Primary Convention refused to endorse him for reelection. Thus, the general election featured Robert B. Crosby as the Republican nominee who defeated Democratic nominee Robert J. Swanson.

The 1948 Nebraska lieutenant gubernatorial election was held on November 2, 1948, and featured former Speaker of the Nebraska Legislature Charles J. Warner, a Republican, defeating Democratic nominee Sam J. Howell.
