MAGA represents a smaller proportion of eligible voters that cannot win elections without the broader support they somehow garnered.
I don't know what the bigger half is capable of learning, some of them probably learned a lot already if they are a shareholder of any kind, and it would not make very much sense for it to remain the bigger half by now. It really was the non-voters that consistently failed to send Trump and his people packing though.
Sickening as it can be sometimes, hindsight is 20/20 and just a short number of weeks ago it would have made more sense for the shareholders of the USA to just cough the money up front and pay him $1Trillion to go away and never come back, taking his kind with him.
Even worse, a year ago his price would have surely been lower, probably one of the biggest lost opportunities some of these shareholders will ever see.
Eventually some Trump voters will notice on their own stock market fluctuations, which of those, what percentage will learn that it is actually Trump's decisions that caused it?
