Wan’t that the Presendetal election and not his first senate race?
The [democrat primary runoff] contest between Stevenson and Johnson was the closest senatorial race in the nation’s history; after Stevenson appeared to be the winner, an amended return came in from Precinct 13 in Jim Wells County, a stronghold of George B. Parr qv, giving Johnson 201 votes and Stevenson only 2 votes; this decided the election in Johnson’s favor, with a total state vote of 494,191 for Johnson and 494,104 for Stevenson.
