If this is a re-alignment election, why?
Because it's
about past time. Re-aligning elections are events that tend to happen approximately every generation or so, and as such we're sort of overdue for one right about now.
And yes, the 2024 re-alignment that polls are suggesting
is real.
There’s also been a lot of digital ink spilled on reasons why men might move away from Dems en masse.
Depending on which surveys you choose to consult, the gender gap has narrowed either slightly or significantly since 2020, but either way the chasm between the two sides appears to have closed somewhat during this time frame. This continues the trend we saw from polling during this spring's primary race, where Trump performed better among women than men while Haley did better with men than women, despite the candidates' own respective genders. Of course the GE electorate will look far different than that of the GOP primary, but this general rule can still be decently instructive for what we'll see in the fall.
