The prediction was that Democrats would be “shellacked” in the November 2022 U.S. midterms, implying a large, wave‑type Republican victory at the congressional level.

What actually happened:

• Senate: Democrats retained and expanded their Senate majority, going from a 50–50 chamber (with the vice president breaking ties) to a 51–49 edge after netting one seat. (ballotwire.com)
• House: Republicans did win the House, but only by a narrow margin (around 221–214 or 222–213 depending on the final count), a net gain of 9 seats – far short of a typical “wave” or “shellacking” for the party in power. Analysts widely noted that the expected “red wave” failed to materialize and that Democrats broadly exceeded expectations. (cnbc.com)

A “shellacking” or “wave” midterm historically means large, double‑digit net House gains and/or loss of the Senate by the president’s party (e.g., 2010 or 2014). In 2022, Democrats not only held the Senate and governorships better than expected, but Republican gains in the House were modest.

Because the real outcome was a mixed, relatively close election with Democrats outperforming historical midterm patterns, the prediction that they would be “shellacked” and face a large Republican wave at the congressional level is best characterized as wrong.
