I take it this son is from his first marriage, --the good loyal wife and kids whom he dumped as soon as he got back on US soil. This young man comes from strong brave military stock, that skipped a generation with his father. John McCain sold his soul years ago for his bowl of political pottage. I'll bet that young skinny young McCain has more integrity than his dad ever had.
He spends no more time with his children from this second marriage than he ever did with the first wife and children.
Despite the fact that Cindy had a stroke, he goes about his world travels with no concern at all for his family.
