The Gathering Crowd: Ohio Gov. John Kasich is expected today to join the gaggle of Republican candidates for president. He’s #26.

PolitiSpeak: Republican candidate Jeb Bush yesterday laid out aggressive plans for taming the federal government, including an immediate hiring freeze, a 10 percent cut in the federal work force, and a constitutional amendment requiring a balanced budget.

>Wisconsin’s Republican Gov. Scott Walker signed a strict new law banning all non-emergency abortions in his state at or beyond 20 weeks.

>Radio foghorn Rush Limbaugh spoke up in defense of Donald Trump yesterday, saying the American people “have not seen an embattled public figure stand up for himself, double down and tell everybody to go to hell.” A right-winger himself who hates the Republican establishment, Limbaugh said Trump will survive having attacked the military record of Sen. John McCain. “Guiding all of this,” Limbaugh said, “is the guiding presumption that the majority of the American people are as outraged as the media are.”

NukeDeal: The UN Security Council yesterday gave unanimous support to the international nuclear control deal negotiated with Iran. Sitting down with NPR’s Steve Inskeep, Secy. of State John Kerry said it would be an enormous mistake if the American Congress rejects the agreement. “I’m telling you, the U.S. will have lost all credibility,” Kerry told Inskeep. And he said that if Iran goes on to develop nuclear weapons and the US conduct a military strike “do you believe the United Nations will be with us? Do you think our European colleagues will support us? Not on your life.”

The Sports Page: Golfer Jordan Spieth, the 21-year-old wunderkind, was upset in his quest to win golf’s Grand Slam when fellow American Zach Johnson won the British Open. Spieth, who had been hoping to make golfing history, was magnanimous in defeat, giving Johnson a big hug.

Billions and Billions: With a $100 million grant from a Russian Billionaire, scientists are about to embark on a new search for intelligent life in the universe.

His summer tour will be his travelling farewell. Keillor says he might do some travelling and see the sights this time. “I’ve been everywhere, and I’ve seen very little,” he said. “I’ve seen a lot of hotels, a lot of airports, I’ve seen the backseats of cabs and I’ve seen back stages of theaters.”
