It's almost like people are complicated and when you are forced to choose between two parties you almost always go for the stronger male person
That seems like an unfair conclusion not rooted in empirical evidence. How do you explain the numerous democratically elected female heads of state? What does "strong" mean here? Do you think that current US leadership is "strong" or merely "loud"?
Like the reptile brain gets enabled if you loose the overview.
> the stronger male person
raises an interesting point (ignoring the "male" part) -- there isn't any real consensus on what attributes indicate "strength" (for instance, there are a lot of people who consider Trump strong, and a lot of people who equally consider him weak).
So the hypothesis could be true, but not terribly enlightening.
