The electoral college is quite literally based on the apportionment of Congress.
Yes, but the disproportionality between electoral votes per voter comes more from the existence of the Senate than it does with the slightly different population sizes of the House districts. Wyoming has almost 4 times the electoral votes per voter than Ohio, whereas right now the widest ratio in House district populations is Delaware’s 980k having 80% higher population compared to Montana’s 542k.
And the genuine unfairness of the electoral college is the winner take all nature of it. Even if the electoral college itself were divided exactly proportionally to the population of the states, there would still be divergence between the national popular vote and the electoral college winner when one candidate wins a disproportionate number of very close states. Apportionment is a separate problem from the electoral college, and both independently need to be fixed.

Plus the incoming Lieutenant Governor is a Democrat. And in the Texas governmental system, the Lieutenant Governor has a ton of power over the Senate, akin to the Senate Majority Leader in most other American systems: ability to set committee memberships, control the calendar, etc.
