Total unadulterated crap.
Are you suggesting that Chris Christie for example should have stayed with his campaign when the state that he was governor of suffered a massive snowstorm?
Or that if a candidate's mother were (God forbid) to suffer a life threatening stroke back in his home state, he shouldn’t go be with her? There is more to life than running for president.
“There is more to life than running for president.”
Then by all means go do those things instead.
