If you think the Hundred Days was a period when FDR "pushed through law after law" and Biden's unpopularity among Republicans means he's not like FDR, you could learn some more about the Hundred Days https://www.washingtonpost.com/opinions/2021/04/26/biden-reaches-his-100-day-mark-his-approval-ratings-suggest-hes-no-fdr/

Yes, Roosevelt got his banking measures through without a hitch; that was the very start of the Hundred Days, on March 9 (remember, Roosevelt was inaugurated March 4 and the special session of Congress started five days later)

In just about a week, when the farm relief bill was before the House, Republicans were calling it fascist and communist. James Beck, R-PA, likened to the power given "to Hitler." Joseph Martin, R-MA, said it put Americans "on the road to Moscow."

(I mention this specifically for people who think “taking away your burgers” was hyperbolic nonsense; they’ve got a way to go yet.)

Congress already, before Roosevelt took office, refused him the power he wanted to conduct foreign policy—a discretionary embargo against “aggressor nations.” During the Hundred Days, Republicans & other conservatives organized to prevent reduction of war debts or tariffs.

He couldn’t get the St. Lawrence treaty either. Taking together the embargo, the war debts, the tariffs, and the treaty, we can say that Congress was most successful in checking him in the area where presidents have the greatest leeway—foreign policy.

Which also tells us that what Congress did, they did because they were ready to do.

Roosevelt didn’t want the Federal Reserve powers that Carter Glass wanted it to have, nor did he want the deposit insurance program that Henry Steagall wanted. He accepted Glass-Steagall because it was what Congress was going to give him in the realm of regular banking policy.

The omnibus recovery bill, which was the closest analog to the current infrastructure bill, ran into tremendous difficulties. Conservatives didn’t like its protection of the right to join a union.

Conservatives began pointing to the success of the earliest recovery measures, saying the economy had already turned upward (it had) and pressing to abandon further legislation.

Congress wrangled over the proposed taxes to fund the public works measures.

Roosevelt wanted the session to conclude by June 10, in advance of the World Economic Conference. But he didn’t want to give up his recovery bill either.

In the end it passed the Senate by only 46-39—with 15 Democrats voting against.

The adjournment on June 16 (officially on June 15; Congress can bend time) ended the “hundred days” (which were not; try counting them yourself).

As Frank Freidel wrote, Congress’s “exhausted members would have scoffed in derision if they had been accused of operating as a rubber stamp to approve Roosevelt proposals."

It’s true that the first legislative push of the New Deal was important: it fulfilled many of Roosevelt’s campaign promises and critically, sparked the economic recovery that continued strong through Roosevelt’s first term.

It also legalized beer.

That (the recovery, not the beer) (well, both) was vital! But if we’re going to draw lessons from that time, we should probably get it right.
