This is an almost exact repeat of history, these events have happened before. The history of FDR, his policies, his personal attitudes, his administration are almost all played out as almost an exact template in our current dictator’s administration.
FUBO & FAD
In a way you're right. After Roosevelt won reelection with 523 our of 535 electoral votes, people weren't going to complain about how the economy was doing. Roosevelt was insulated from criticism because voters just couldn't take Hoover and the Republicans any longer. They just assumed they were better off with FDR, that he'd given them everything, and didn't demand as much from him as they did from other leaders.
There's also some Bill Clinton in the present situation. If a president can turn a funeral or a natural disaster into an "I care" moment, it can do a lot for his standing in the polls. I don't think most Americans regard Obama as their family's savior as they did FDR, but right now the Clintonesque style, which supporters regard as being empathic and opponents consider narcissistic, is working for Obama.
The difference from Clinton is that the economy was actually doing well in the Clinton years. The difference from Roosevelt is that FDR didn't quite have the press in his corner or back pocket. The old chestnut about reporters being Democrat and publishers being Republican was actually true in the 1930s, and a lot of newspapers that are now Democrat, were still solidly Republican in the Thirties, at least as far as editorial endorsements went.
