Don't disagree with you in principle but 2024 saw a very, very, very large turnout for US standards - the biggest one... Kamala's 75m+ votes basically are good enough (by very wide margin) to win any previous election (slimmer margin in 2020 than others but you get my point...)
2020 had about 4 million more votes cast.

Lots of people don't vote in mid terms, that's what Trump is aiming for.
