Them please show me what President since WW2 had a mandate.
The rest of your points are as hoc criticisms and red herrings. Please stay on task and use logical argumentation.
Richard Nixon in 1972 won 49 states, 61% of the vote, and over 500 electoral votes. In 1984, Ronald Reagan won 62% of the vote, 49 states, and over 500 electoral votes. In 1964, President Johnson won 44 states, 60% of the vote, and over 450 electoral votes. What level do you think should be reached before it is called a mandate?
In addition to the above elections, lesser but convicing elections were won by the Republicans in 52, 56, 80, and 88, 2008, and 2012. Democrats won convincing margins in 48, 92, and 96. The elections that were even near close were 60, 68, 76, 2000, and 2004.
How can you possibly say there have been no mandates since WW2? There are many more mandates than close elections. Is it because that leftist mandates seem quite rare?
