Trump is an insurgent outsider. He is our first populist President.
His Inauguration address was a scathing rebuke of the Uniparty establishment.
He sees himself as the tribune of the Little Guy from Main Street USA.
That's really what Andrew Jackson was which is why the comparisons are being made with Trump.
Jackson's supporters were regarded as little more than a mob by those who had become comfortable thinking of themselves as an elite entitled to rule.
