You know, I wonder if that's a sad but valuable trait for a politician.
Public opinion can change daily, and external events can appear with no warning. These things can make a prior path of action vanish, or even make it madness to pursue.
If you try to plan everything long term, I bet you hit a lot of disappoint as a politician. If you only see today, then you're not fighting for things that are now not possible.
I imagine one would be far less stressed as a result. And maybe more popular than otherwise.
Some problems require years or even decades to address. Consider how quickly a COVID vaccine was developed, yet it depended upon many years of quietly studying SARS and R&D around MRNA. Or consider trying to address developing or maintaining infrastructure.
A chaotic politican whose mind is changed by the last person they spoke with won't do well facing serious long term problems.
It gets worse if the only things they consistently stand for is their own power, personal wealth, their sycophants, and their grade-school-level (mis)understanding of complex matters.
He seems to care immensely about being viewed as the "winner" and the "best" at everything.
I also have to assume that anyone interested in slapping their name in big gold letters on as many buildings as possible is interested in the perception of legacy.
