Fortunately, more voted for Harriet Tubman. Tubman escaped slavery to become a leader of the Underground Railroad, then repeatedly returned to slave territory to help others escape. Tubman would be a good choice. What's more libertarian than helping people escape slavery and resist being governed without their consent? None of these people reach 10% of the significance of Alexander Hamilton.
This is an attempt to give unearned credit for the sake of aggrieved feelings.
Tubman checks off two boxes; black and female.
Jackson stays ‘cause he was the first democrat President.
And yes, the democrats have no shame.
