It wasn't the leftists that started tearing down Hamilton (if you want to get techincal, FDR was the first person to start ripping Hamilton, and he also bad mouthed Jefferson), but everyone else.
If you go back to the time frame, the men hated each other, Hamilton died young, Jefferson didn't, and his supporers didn't.
Jefferson and his friends spent years and years tearing down Hamilton after his death while building up Jefferson (who I actually am quite fond of, though I admire Hamilton more).
But not every liberal likes Jefferson just as not every conservative likes Hamilton.
A good example would be Robert Rubin whose role model was Hamilton and who went so far as to build a bust of him to admire every day while Senator George Allen is a huge fan of Jefferson and quotes him often (as did Reagan many times).
The destruction of Hamilton's reputation became long before FDR was even born. He was hated throughout the South during the entire 1800s mainly because of Jefferson and Jackson's insanity about the Bank. Newspapers during the 1790s went out of their way to lie about him, his program and his intentions.
Not praising Jefferson in Virginia would be political suicide. I see little to admire in Jefferson whom I consider to be a form of "limosine liberal". Though I used to believe the conventional propaganda about him.
