Will this week's blue wave election usher in a Democratic president in 2028?
A CNBC analysis of historical election data finds wave elections don't necessarily spell trouble for the party in power during the next presidential year.

TL;DR
- Historical analysis of midterm elections since 1938 shows that the party in the White House losing seats in a midterm does not guarantee a loss in the subsequent presidential election.
- The recent election's losses for the incumbent party rank 10th in terms of House seat loss since 1938.
- Major midterm wave elections, such as those in 1938 and 2010, did not prevent the incumbent president's party from winning the subsequent presidential election.
- Conversely, midterm losses for the incumbent party have preceded presidential election losses for that party in some cases, like 1958 leading to 1960 and 2018 leading to 2020.
- The outcome of presidential elections is significantly impacted by the quality and appeal of individual nominees, which can outweigh the broader political environment and midterm results.
