The spectacle began with Donald Trump saying on Fox News that Ted Cruz’s father was with President Kennedy’s assassin shortly before he was killed: “His father was with Lee Harvey Oswald prior to Oswald’s being — you know, shot.” You hadn’t heard? Well, unlike Trump, you apparently don’t get your news from the National Enquirer, which recently published that accusation with accompanying photo.

Cruz, knowing that a loss in Indiana would doom his candidacy, snapped and vented his deepest views about his opponent, which is almost always a mistake. He called Trump “a pathological liar. He doesn’t know the difference between truth and lies. He lies practically every word that comes out of his mouth.” He went on to describe Trump as “utterly amoral,” “a serial philanderer,” and “a narcissist.” Trump responded with a statement saying “I have watched Lyin’ Ted become more and more unhinged as he is unable to react under the pressure and stress of losing.”

Forgive me, but these are eight-year-olds. The logical next step was for them to start wrestling and bite each other.

To state the painfully obvious, this is not how leaders behave. It’s pretty much the opposite. Voters’ memories (and the video) of them acting like snippy brats won’t go away, and the things they said cannot be taken back or glossed over. Any hope of uniting the party behind Trump, now that his victory last night virtually assures him the nomination, is gone. Cruz attracted a substantial following, but now, having quit the race, it would seem impossible for him ever to endorse Trump.

After all the incredible twists and turns in this race, the biggest reality hasn’t changed: Hillary Clinton is the most likely next president, just as she was a year ago. I’d be crazy to make any confident predictions, but it’s hard to imagine how the wisdom of Reagan’s commandment could have been demonstrated more dramatically than it was yesterday.

Takata to recall another 35 million airbags

The Primary Results

Cruz exits race after Trump's Indiana victory

Ted Cruz suspended his campaign after Donald Trump easily won the Republican primary in Indiana with 53% of the vote. Trump tried to be generous toward Cruz in his victory speech, calling him "one hell of a competitor." From a field that started with 17 Republicans, Trump now faces a clear road to the nomination. Washington Post

Cruz's uncompromising conservatism failed 

His belief that staying true to his conservative values would win the day proved wrong. John Kasich will remain in the race, still hoping for a contested convention and arguing that he's the best candidate to win in November. Fortune

Sanders wins while Clinton looks towards November 

Bernie Sanders won a surprising victory in Indiana with 53% of the vote; he says he's not ending his campaign and the race isn't over. Hillary Clinton all but conceded Indiana to Sanders by reserving funds for the national race and turned her sights on Trump.  NBC News
