Musk's full support for Trump has a clear answer; he's already stated it very clearly. You may doubt a politician's vision, but don't doubt the vision of a tech-born entrepreneur, especially one who's the richest person on Earth.
Musk has publicly addressed this issue, and I'll summarize his points:
1. The Democrats have sent a large number of immigrants to swing states.
2. In the future, there will be no swing states in America, resulting in a one-party dominance.
3. Future presidential elections in America will be meaningless.
4. All states will become 'California-ized', leaving voters with nowhere to go.
5. Regulatory bodies will increase, severely restricting the development of businesses.
6. Too much regulation will lead to very low rocket launch efficiency.
7. Landing on Mars is a long way off.
8. In the future, aliens will say: Look, they were already ready with rockets, but unfortunately, there was too much regulation.
This raises another contradiction: Trump's economic policy is anti-globalization, whereas Musk's Tesla cars are beneficiaries of economic globalization. #你问我答
