It's not 49%. The split in 2024 was 1/3 R, 1/3 D, 1/3 didn't vote, and ~1% 3rd party.
As the other commenter said, it's a much fewer percentage of the population that sways those 1/3s either in the favor of R or D.
And you'd think Democrats would have chased after the 1/3 that sat at home instead of Rs, but we all know what actually happened
