I, for one, do not miss the days of GOP candidates folding up like cheap suits every time the Rats fling obvious lies at them. It was Romney himself who filled the voters with anger and disgust when he caved to Candy Crowley's unethical criticism when he dared to accurately quote Obama re: Benghazi. He not only failed to assert himself, he phoned in the rest of the entire campaign.
Romney his own self ensured the rise of a candidate like Donald Trump. It's little wonder he takes Trump's style as a personal affront to himself, because it is.
