WA:The NYT has a well-documented article on Trump in Atlantic City and an editorial by Peter Werner.  Here's a paragraph from the OpEd piece.  Both articles are well worth reading.  "Mr. Trump knows his target audience, which explains why, beginning the morning of the Indiana primary on May 3 (the day he became the de facto nominee), he has — among other in-the-gutter moments — implied that Senator Ted Cruz’s father was implicated in the assassination of President Kennedy; insinuated that Vince Foster, a friend of the Clintons who was White House deputy counsel, was murdered (five official investigations determined that Mr. Foster committed suicide); engaged in a racially tinged attack on Gonzalo Curiel, a district court judge presiding over a fraud lawsuit against Trump University; and expressed doubt that a Muslim judge could remain neutral in the case. This is conspiratorial craziness and rank racism — and all of it has happened after we were told Mr. Trump would raise his game."
