Earlier quoted context omitted.
That didn’t happen with Bush, who conjured up a premise with multiple lies in order to justify going to war. And then 3 years later, he got re-elected.
That was by far the most disappointing US election. Electing a bad president is clearly a risk of democracy, but re-electing a bad president, that's incomprehensible. And yet that was the only presidential election in decades where the Republican candidate got the majority of the votes.
That election was 2004 of course. Reagan got 58.8% in 1984, so two decades prior (decades as you noted).
Obama got 52.9% in 2008. And prior to that for a Democrat? More than two decades prior, wherein Jimmy Carter barely scratched out a majority popular vote at 50.08% in 1976.
Lyndon Johnson of course got 61% in 1964. The monster that put us deep into Vietnam and wrecked the country got the highest popular vote percentage for the Democrats in the past century.
The two highest in modern US history, Lyndon Johnson and Nixon. What does it say about the people of the 1960s and 1970s? It says a lot of terrible things about their ability to judge character and make rational decisions.
