“It says Bush thinks taller people are winners and shorter people are losers.”
That is true. All things being equal, people tend to choose a taller person than a shorter person. Obama is tall and that helped him pull in voters.
A body language expert likely told Bush to stand tall and on the tips of his toes when the pictures were made.
Agreed. But probably unsaid was, "and don't get caught doing it." Can't wait to see the Trump commercials and comments about that.
