I have no problem with the current nickel, or the pre 2006
Jefferson nickels.
I would be in favor of putting Liberty on all our coins
As for Jefferson, I would not put myself in his camp.
I think he did a good job on the Declaration of Independence.
But....
Jefferson had so much love for France, I feel he made bad decisions for America when dealing with them. When Vice President under Adams, he did not like Adams policies with France, so he would send letters to France to let them know what Adams was doing.
Although making the lousianna purchase was a good thing for America, it was not really legal how he did it. Jefferson was against a strong federal government, he was not of the Federalist Party, but he like using the power once he became president.
When he was Secretary State and Vice President, if he did not like what was going on, he would go home, for long periods of time.
As far as Sally Hemings, I really don't see anything wrong with it. She was either 1/2 or 1/4 ...maybe less, African/slave. She was Jefferson's deceased wifes half sister. When they were in France most wrote of her, of how beautiful she was. And no mention of her being a slave. She could have stayed in France, and lived free, but made the choice to go back to America with Jefferson.
Jefferson never freed his slaves, because he owed so much money on them. He did not like banks, but like to borrow money and live beyond his means.
He did give Sally Hemings papers that sort of said .. She was on vacation.
And set her up with a small house, that he spent a lot of time in.
Of course all this is my opinion, from what I read. I like reading books on the presidents, but then a lot of that information is the authors opinions.
