The defintion for discouraged workers changed slightly in 1994 (adding a requirement to have looked for work in the last 12 months), but discouraged workers, who had never been systematically covered, were not counted at all after 1967. Educate yourself...First, someone else's blog asserting something is not an actual cite...it's just another claim. Look at the actual information and official definitions.
Following are links to the BLS publication "Employment and Earnings" from selected years...
July 1960 Near the end, in Explanatory notes, 2-e (59 on the pdf) gives the definition of Unemployed as
Unemployed Persons comprise all persons who did not work at all during the survey week and were looking for work, regardless of whether or not they were eligible for unemployment insurance. Also included as unemployed are those who did not work at all and (a) were waiting to be called back to a job from which they had been laid off; or (b) were waiting to report to a new wage or salary job within 30 days (and were not in school during the survey week); or (c) would have been looking for work except that they were temporarily ill or believed no work was available in their line of work or in the community. Persons in this later category will usually be residents of a community in which there are only a few dominant industries which were shut down during the survey week. Not included in this category are persons who say they were not looking for work because they were too old, too young, or handicapped in any way.
The bolded part is what we now call "discouraged workers," plus the temporarily ill.
January 1970 Page 144 of the publication, 141 of the pdf, The definition is now
Unemployed persons comprise all persons who did not work during the survey week, who made specific efforts to find a job within the past 4 weeks, and who were available for work during the survey week (except for temporary illness). Also included as unemployed are those who did not work at all, were available for work, and (a) were waiting to be called back to a job from which they had been laid off; or (b) were waiting to report to a new wage or salary job within 30 days.
Note the new requirement of having looked in the previous 4 weeks, and the exclusion of people who gave up looking.
In 1976 alternative measures were introduced, with U-5 as the official rate and U-7 including discouraged workers. The alternative measures were redefined in 1994

And please learn to do your own research, not take someone's blog as Gospel. The only change in definition of Unemployed under Clinton was that people waiting to start a new job still had to have looked for work in the previous 4 weeks.
