At some point today, Mitt Romney will make the case against Trump for President:

Mitt Romney will call Donald J. Trump “a phony” and “a fraud” in a speech on Thursday in which he will urge Republicans to rally around one of Mr. Trump’s presidential rivals, according to excerpts from his remarks.

The hastily organized speech, to be delivered in Utah, represents a last-ditch effort among leaders in the Republican Party to blunt Mr. Trump’s momentum before he runs away with the presidential nomination. Mr. Romney has been criticizing Mr. Trump on social media in recent weeks, calling on him to release his tax returns and arguing that slowness to denounce the Ku Klux Klan was disqualifying for a presidential candidate.

“Donald Trump is a phony, a fraud,” Mr. Romney will say. “His promises are as worthless as a degree from Trump University. He’s playing the American public for suckers: He gets a free ride to the White House and all we get is a lousy hat.”

The impact?

Absolutely zero.  In fact, it could bolster Trump.

A member of the GOP establishment, and one who lost the last election, slamming Trump?  This is exactly  what brings people to Trump in the first place.  I am amazed that Romney among others have not figured this out yet.
