The prediction was that a reform/clarification of the U.S. Electoral Count Act could pass the Senate in the 2021–2023 Congress with at least 60 votes if pursued, i.e., that such a bill could attract substantial bipartisan support.

In reality, during the 117th Congress, the Electoral Count Reform and Presidential Transition Improvement Act of 2022—which specifically reforms and clarifies the 1887 Electoral Count Act—was introduced on a bipartisan basis and folded into the Consolidated Appropriations Act, 2023. It passed the Senate on December 22, 2022, by a 68–29 vote, well above the 60‑vote threshold, and was signed into law by President Biden on December 29, 2022. (en.wikipedia.org)

Since a substantive Electoral Count Act reform did in fact receive 60+ votes in the Senate within that Congress, the core feasibility claim in the prediction—that such a reform could get 60 votes—was borne out by subsequent events. The counterfactual element about Biden “prioritizing” it is not directly testable, but the observed outcome confirms that the vote count threshold was realistically achievable, so the prediction is best classified as right.
