You can cut it any number of ways: the CHIPS act has existed in some form or another since 2019, but it only gained legislative momentum when Biden threw the weight of the executive branch behind it. The IRA was probably going to happen in some form, but the concrete scope and priorities listed in it come directly from Biden's legislative agenda[1].

TL;DR: 100% credit? Of course not. But has Biden's administration been more effective at advancing its policies through the legislative than the previous administration? IMO yes.

I don't think it's a coincidence that the two presidents in modern history who were most effective at passing major legislation (Biden and LBJ) had spent decades in the Senate.

The fact of repeatedly managing to get cooperation out of a divided congress was one of his superpowers.
