There were many LSI American presidents in the 19th century (and both Jefferson Davis and Alexander Hamilton Stephens were LSI, Davis Se subtype, Stephens Ti subtype), and they were prominent in American politics in the 19th century, but after 19th century, there were no LSI presidents except maybe Truman (was he an ESI-Se?). Bobby Kennedy did come close; but actually I want to make the focus of this thread the Sensory subtype; I can understand the political situations of LSI Ti a bit better.
LSI-Se can't make it into the Presidency anymore, they tend to hold non-mainstream views and the Ti subtype which is more into unifying and holds more mainstream views has come closer but Hillary Clinton, Mike Pence still didn't make it.
The two main reasons I can think of are what I just mentioned, and male LSI-Se are rare.
But what else? How could LSI-Se womens' beauty, unusual experiences, uncommon knowledge, and intellect not help them into the presidency? LSI-Se men are also good looking, how does that not help them? How could Tulsi Gabbard get so few votes when she was so beautiful and so intelligent? Why do the Democrats care so little about aesthetics or are even bothered by beauty?
