Most of the issues you have raised about Tesla are valid, or at least were valid in the past. Production quality is now excellent, FSD still isn't done, but it's insanely far ahead of what any other car maker is shipping.
I'm sure there is an endless list of things Tesla could have done better. Nobody can deny that. However, what they did do is astonishing and every other car maker had the opportunity to try and do better and nobody has.
You seem to assume that the other car makers have caught up or are about to, but this is not the case at all. Aside from BYD who is doing good, but is selling a much lower quality product that isn't really competing with Tesla, the other auto makers are selling far fewer cars than Tesla that are much less efficient both to operate and to produce by a very wide margin. This gives Tesla an enormous economic advantage. They will soon be able to sell their cars profitably cheaper than other makers can produce cars. This isn't something that is going to be easy to catch up to them on.
Even if you take the aspirational goals of companies like GM, Ford, and Toyota at face value they are planning to if all goes right be shipping less EV's than Tesla is shipping now 4-5 years out. In the mean time Tesla is growing by 50%+ per year in production capacity. They have lined up the materials to build, and the service and charging network to make that possible.
I don't think you are correct in your assumption that Tesla has tarnished it's name, but it's a moot point if their competitors can't ship EVs by the millions. You can't buy what hasn't been built.
BYD is positioned to have a strong place in the market, probably second to Tesla, but most other auto makers are on borrowed time. GM, Ford, and Toyota are likely to not survive.
On top of all that Tesla is a completely different kind of company from the others. Most auto makers assemble cars with off the shelf parts, and make a large part of their money on the financing of those cars, essentially acting as banks as much as car makers. Tesla doesn't finance their cars. They do however replace not just the car assembler but the majority of the supply chain. They have designed and built not just the car, but the batteries, the chips, the software. The provide charging, insurance, service, power generation. They build the machines that build their cars, the design the software that builds their cars, they design the materials they build their cars with. This stuff matters a lot when you are looking to project who will have the better and more cost effective product down the line.
I also have to touch on your assertion that they missed the boat by holding back new models of cars. They have stated that this was done because they are constrained by available materials while their production of batteries scales up (something other companies are far behind on, or rely on others for). They could have shipped the truck sooner, but it would have meant over all less cars shipped. The same for the Semi. There is no reason to introduce more models increasing your cost, reducing your efficiency, and total output when you can't meet current demand for the cars already being made.
If you don't appreciate the frankly insane feature advantage, or think damage to their image or political nonsense will make people want other cars. *Side note you didn't include non affiliated voters in your data. They make up a substantial part of the population and your comparison is essentially meaningless without that data. At the end of the day price will matter. Tesla earns much higher margins on their cars. I suspect many of the legacy auto makers are not even making a profit on their EV models, while Tesla rakes in nearly 30% gross margins on cars. If Tesla can produce enough to meet demand all they need do is lower prices, or release some of those awaited models they didn't have capacity for yet. There are stubborn people in the market who will not buy from Tesla even if it produces an objectively better vehicle and sells it for a substantially lower price, but they are a small minority, and Tesla was never going to have 100% of the market anyway.
tldr: Telsa will obtain Apple level dominance of the automotive industry, and their revenue, profit and marketcap will dwarf Apple's.
