Anyhow, size does matter... Of one's heart. trump, Cruz and Rubio all have hearts that make the grinch's (pre enlargement) heart seem yuge. That Rubio cannot beat two incredibly detestable people is an indictment of Rubio, big or small handed.
From here out, the challenge for Hillary Clinton is to attack Trump cleverly: to demonstrate that she can be strong but not strident, smart but not condescending, etc. All of this is harder for women due to sexism. However, she does have a key advantage: Trump is pure, unadulterated slime.... That even some conservatives are running away from.
