I think what you said is the right angle....

By not obsessing over "never offending anyone", DJT displayed confidence. He is not going to pander because he is not a slave to your opinion of him.

Meanwhile the duplicitous leftist candidate, who painfully crafts messages designed to be "inclusive to all" winds up appearing weak and needy. They are in a sense a slave to public opinion.

Simple laws of attraction, as exemplified by boy-girl interactions, show that people are repelled by weakness and are attracted to strength.
