Donald Trump is of course known for what many would call extreme statements. These alpha and hyper-alpha verbal messages coexist with similar magnitude paralanguage (e.g., vocal qualities) and body language.
The images included here however, are nonverbal examples of what are known as "Alpha-Beta Hybrids" (of which there are many). While these hand gestures are still alpha in their emotional tone (dominant, aggressive, assertive) - they're significantly muted by the flexion of Trump's forefinger (index finger). This is to Trump's advantage (or Clinton's or Sanders', etc.) as it projects these same alpha qualities while avoiding being overly aggressive.
Hyper-alpha behavior (of all types) will solidify one's political base but has a strong tendency to alienate undecided voters.
Of these two examples the one above is a bit more beta because of the modest palm-up orientation while plane of the hand of the configuration shown below is more vertical - and thus a bit more alpha.
Although this particular nonverbal display wasn't "invented" by Donald Trump - it's relatively rare and few others currently use it. Because of Trump's success to date, there's little doubt that in the future other politicians will use this gesture more frequently.
As the general election draws nearer and the two party "leaders" have been chosen, it's very typical (though not universal) for the candidates (in pursuing the independent voters) to use less extreme nonverbal behavior.

In an effort to be both practical and academic, many examples from/of varied cultures, politicians, professional athletes, legal cases, public figures, etc., are cited in order to teach and illustrate both the interpretation of others’ body language as well as the projection of one’s own nonverbal skills in many different contexts – not to advance any political, religious or other agenda.
