The prediction was that after the November 2021 elections, Republican politicians and media would rapidly stop alleging that U.S. elections are rigged or stolen and would largely drop 2020-election-fraud rhetoric, "overnight" and within months (by mid‑2022).

By mid‑2022, that clearly had not happened:

• Donald Trump was still explicitly claiming that the 2020 election was "rigged and stolen". On June 9, 2022, he posted on Truth Social that January 6 was about an election that was "Rigged and Stolen," and PolitiFact noted he had shown "no signs of backing down" from that claim. (politifact.com) On June 19, 2022, he again described the 2020 election as "RIGGED & STOLLEN" in a public statement, as documented by Snopes. (snopes.com) Trump is the leading Republican figure; his continued rhetoric alone contradicts the prediction.
• High-profile Republican candidates in 2022 were still centering campaigns on false stolen‑election claims. For example, Arizona GOP gubernatorial candidate Kari Lake repeatedly called the 2020 election "stolen" and "corrupt" and used these claims prominently in a June 2022 primary debate.

• Systematic analyses of 2022 midterm candidates show election‑denial rhetoric remained widespread well past mid‑2022. CBS News found that, as of early November 2022, 308 of 597 Republican federal and statewide candidates had raised unfounded doubts about the 2020 election, including many who explicitly said it was stolen or rigged. (cbsnews.com) The Washington Post similarly reported nearly 300 GOP "election deniers" on the 2022 ballot, noting that the movement arising from Trump’s effort to overturn 2020 was, in many respects, even stronger two years later. (washingtonpost.com) Academic work from Stanford also characterizes 2022 as a cycle in which a large share of Republican statewide candidates questioned or denied the 2020 results.

Because prominent Republican politicians and a substantial share of GOP candidates were still actively using 2020 stolen‑election rhetoric well into and beyond mid‑2022, the forecast that such claims would quickly stop and effectively disappear was not borne out.
