The day before Super Tuesday, The New Yorker's Amy Davidson looks ahead to tomorrow's big primary contests.

But first, she stopped to discuss the "screamfest" between Donald Trump and Marco Rubio that started with last week's GOP debate and continued over the weekend, with the two trading barbs over each other's appearances.

Davidson said the establishment GOP ultimately has to determine what it doesn't like about Donald Trump:

"Is the problem that he’s too tacky to be a presidential candidate, or is the problem the bigotry, the xenophobia, the scorn for religious freedom...?"

"[Trump] almost would rather be associated with Mussolini than to be thought a fool for not knowing it was a Mussolini quote." @tnyCloseRead
