I believe you are misrepresenting the facts.
State legislatures have never awarded electoral votes based on makeup of state legislature. You have conflated and confused the history of electoral votes. Initially the electoral votes were apportioned based on popular votes. If they had done it your way, there would never have been a general election for president. It was only later states changed the mechanism for electoral determination to one where most states now award all electoral votes based on winner of popular vote. There are some caveats, which I will not go into.
The problem is you continue to ignore the reality of Trumpism which does not recognize the law as you think you know it. Do you really think Kari Lake cares what you believe? If she says there was fraud, guess what ... Republicans in AZ will overturn the election results.
Head in the sand is not a good look
State legislature choose the electors in our early days. There wasn’t any modern political party back then. That didn’t come about until Andrew Jackson bolted the Jefferson’s Republicans to form the Democratic Party as old hickory was angry at the House of Representatives for choosing J.Q. Adams as president.
In 1800 for example, of the 16 states that took part in the 1800 election, six (Kentucky, Maryland, North Carolina, Rhode Island, Tennessee, and Virginia) used some kind of popular vote. In Rhode Island and Virginia, voters elected their state's entire Electoral College delegation at large; Kentucky, Maryland, North Carolina, and Tennessee all used some variation of single-member districts. In the rest, 10 states the electors were chosen by the state legislature.
In 1816, in the following states, the state legislatures choose the electors. No popular vote. Connecticut, Delaware, Georgia, Indiana, Louisiana, Massachusetts, New York, South Carolina, Vermont.
In 1824 when Jackson won the popular vote, but the House of Representatives went with J.Q. Adams as president, the following states let their state legislature select presidential electors: Delaware, Georgia, Louisiana, Maine, New York, South Carolina and Vermont.
As I stated, it wasn’t until after the civil war that all states went to the popular vote.
As for Trump, he’s a has been who doesn’t know it yet, nor does his followers. Apparently a quite a lot of Democrats don't realize that either. Trump will never win another election. Trump is the biggest asset and help the Democrats have going for him. Without Trump, you’d be looking at a red wave election this year instead of minimal losses. If I was a Democrat, I’d be sending Trump a thousand thankyou notes for all the help he’s given to the Democrats this year.
Historical average for 4 presidents excluding Biden since his midterm hasn’t happened yet. Approval average, 39.25% house seats lost 48.5, senate seats lost 6, 4.25 governors lost.
Biden 2022 42% ?????? projected loss of 11-13 house seats, gain of 1 senate seat, a gain of 3-4 governors as of 12 October
Trump 2018 40% lost 44 house seats, 3 senate seats, 6 governors
Obama 2010 42% lost 63 house seats, 6 senate seats, 4 governors
G.W. Bush 2006 33% lost 33 house seats, 6 senate seats, 6 governors
Bill Clinton 1994 42% lost 54 house seats, 9 senate seats, 1 governor
Historically, this midterm makes no sense. But anything involving Trump makes no sense.
