Greatest Democrat/Republican?

Sittin' here watchin' the debate, and a question popped into my head that I think would be fun to discuss.  Who's the greatest Democrat, and the greatest Republican, in U.S. history?

ummm in my opinion for the democrats is JFK for the republican i say Ronald Reagan

One of the greatest dem's. In my opinion is Bill Clinton.

Republican? Dunno

None of them.

Democrats: FDR

Well, here aremy choices:

Democrat: Jefferson.  The Democratic party can be traced back to him.  While maybe not as true a Democrat as some moderns, he was nonetheless a liberal, and the greatest man the Democratic Party's lineage has produced... IMO.

Republican: Thaddeus Stevens
