Forget a brokered convention. It would do as much if not more harm to the Republican party and the country as nominating Donald Trump. Forget a third-party run. Whatever Mitt Romney is thinking, it’s wrong. Lastly, forget voting for John Kasich or Marco Rubio. Their chances are approaching absolute zero. The only thing that can prevent Donald Trump from getting the GOP nomination and handing the country over to Hillary Clinton is if discerning Republicans coalesce around Ted Cruz.
