My first link illustrates that the electorate continues to tilt left/progressive as 1.8M voters over the age of 55 die every year, 5k per day (per the CDC); those voters lean very far to the right. 4M voters turn 18 every year, they lean very far to the left (including women [1]). The data should not be evaluated as a snapshot in time, but instead viewed as a sliding window, as a demographic system. This is not politics, importantly; this is demographics, with political outcomes being the resulting output of the system.

My second link was the wrong link, thank you! I have updated that link to a 2024 election cycle link.
