It has been alleged for years that Johnson captured his Senate seat through fraud, but the book, "Means of Ascent,", by Robert A. Caro, goes into great detail to tell how the future President overcame a 20,000-vote deficit to achieve his famous 87-vote victory in the 1948 Democratic runoff primary against a former Governor, Coke Stevenson. (Source: The New York Times, February 11, 1990.)
I don't have access to the book, and I couldn't find any other reference for those details, but in a news article published on Victoria Advocate.com, titled "Election Fraud Never So Flagrant As With LBJ's Box 13," it is written:
We still hear about election fraud today, but generally nothing quite so flagrantly evident as it was with Box 13. Not that he potential does not still exist for such, like recent reports in New York that there are some 77,000 people in that state's new database of registered voters who are deceased - some who are said to have somehow castes votes from the grave.
It is not always easy to understand just how that happen, but it does, as it did in 1948 in Texas.
It is clear that the string of words "as it did in 1948 in Texas" refers to deceased person who 'would have' voted in that election.
Therefore, the questions are: What was the influence of deceased people to the Johnson's election? Can they actually have led to his election?
