A rare and somewhat enigmatic political map of the United States, issued by the United Steelworkers in advance of the Election of 1972 and just a year after the 26th Amendment lowered the voting age to 18. This brought some 11.5 million new potential voters into the electorate, whom the union no doubt wanted to bring into the Democratic camp.
Each state on the map bears figures indicating its number of Representatives and the number of 18-20 year olds in its population, along with a note on whether it had lost of gained seats as a result of the 26th Amendment. Small stars denote states with Senate races in 1972, with black stars indicating “critical” races, and states shaded yellow would be holding presidential primaries (Though the primary system is prevalent today, most states only adopted it in recent decades, having previously favored nominating conventions.)
One would have expected the 26th Amendment to be a huge advantage for the Democrats, particularly during the tumultuous years of the Vietnam War. They did indeed gain two seats in the Senate, but Nixon won re-election, and the Republicans gained 14 seats in the House.
