Will this week's blue wave election usher in a Democratic president in 2028?

A CNBC analysis of historical election data found that wave elections do not reliably predict defeat for the party holding the White House in the following presidential cycle, undercutting the assumption that this week's Democratic blue wave signals trouble for Republicans in 2028. The study examined past wave elections and compared them with the party's performance in the next presidential year, concluding the connection is weaker than commonly assumed. The findings matter because both parties are already framing this week's results as a verdict on the incumbent administration and a preview of the next presidential race. What to watch next is whether the historical pattern holds as early 2028 polling and candidate fields take shape.
