Since the Dems started in 1792, and Hanson was President in 1781 ( and died in 1783) I doubt if he can be called a Democrat.
"The Democratic Party is one of two major political parties in the United States, the other being the Republican Party. The party under its present name was established by Andrew Jackson during the 1820s, but it traces its origins to Thomas Jefferson and the Democratic-Republican Party in 1792."
