No--it was a Republican vendetta against FDR.
Wrong, Congress and state government were dominated by dems at the time, to get 2/3 of Congress and 3/4 of states you needed more than vengeful republicans
Also the 22nd amendment does more than 2 term limit, it sets the order of succession
I wouldn't be surprised if most of the "yes" votes from Democrats came from conservative anti-FDR Democratic legislatures. I remember he wasn't that popular among conservative Southern elites, even after he died. He was after all a liberal.
Southern Elites made their accommodations with FDR. FDR was prepared to accept South Carolina's James F. Byrnes as his running mate in 1944 until Big Labor nixed the pick. It was Harry Truman and his FEPC who caused the Southern Elites to see him as a threat to States Rights and Home Rule.
At that time, no Southerner had led the Democratic ticket, and the leading Southern candidate for the Presidency, Sen. Richard Russell (D-GA) was not acceptable to the Big City Bosses and Labor. What the South wanted was to ensure that the Presidential candidate nominated would be the least likely to challenge "Home Rule". (That, by the way, was why the South went for Stevenson in 1952 and 1956; Conservative Southerners HATED Estes Kefauver and viewed him as a Scalawag of sorts.)
