Clinton was re-elected in 1996 with only 49% of the popular vote.
The papers claimed that Reagan's trend lines were down, too...and you can see the surprise on the faces of liberal news anchors to this very day if you watch some of the old broadcasts from November 1980 and 1984.
What nonsense. Reagan presided over an economy that was recovering very nicely from stagflation. Inflation was gone, oil prices were low, the stock market was booming, and millions of jobs had been created in 1983. Utterly unlike now. The Democrats of 1984 always expected to lose, so I don't know where this "surprise" nonsense of yours is coming from. Reagan was always comfortably ahead in the polls with approval ratings off the charts, running comfortably on peace and prosperity.
