>>The 18 year old vote came out of the 60s, so did the lowering of the drinking age, the laws were changed in the early 70s.
Half right. Drinking age was raised in the ‘70s due to the Mad Moms. Many states had an 18 drinking age.
The lowered drinking ages came out of the 1960s, although the actual legislation going FROM 21 to 18 took place in the very early 1970s, 1971, 1972, 1973.
Since there were variations among the states, that is a general statement encompassing the overview for the nation.
The raising of the drinking ages BACK to 21, that you are talking about, came about in the 1980s.
