Was Thomas Jefferson the founder of the Democratic Party? Or was it Andrew Jackson? I know that historians call Jefferson a Democrat-Republican, but others say he was the founder of the modern Democratic Party. Also, Jackson was a Democratic-Republican, but he later founded the modern Democratic Party. The Democratic-Republican split into 2 factions: the National Republicans which became the Neo-Whigs, which then became the Party of Lincoln; and the Old Republicans (of which I am one) which became the modern Democratic Party. Is it more true to say that Jefferson was not a Democrat but rather they have their roots in his D-R party, or is it more true to say that he outright founded the Democratic Party as well as the Republican Party (the original name for the D-Rs was the Republican Party--which drove out the Federalist Party)? Finally, in your opinion, would Jefferson be ever so slightly closer to a Republican today, or would he be ever so slightly more a Democrat?
