Hillary still has delusions about making another run for the presidency, so she feels like she needs to keep up appearances. Hillary’s coat and scarf ploy is like the guy who wears a cheap toupee and thinks he has everyone fooled.
I think you’re right about Hillary running for president. I don’t recall her being this busy before. She is here, there, everywhere - book tour, India, Australia, commencement speaker, daily soundbites, creepy late shows, now a Memorial Day Parade.
