Power Sheet – April 11, 2016

-U.K. Prime Minister David Cameron will be trying to climb out of a hole after the Panama Papers showed that his father housed an investment fund in an overseas company. Cameron acknowledged that he had invested in the fund and had sold his stake at a profit of $30,500 shortly before taking office. He also felt compelled to promise that he would release years of tax returns, which no leader of any U.K. political party has ever done. He’ll certainly be taking heat on the issue today in Parliament, but the problem is unlikely to be politically fatal. His challenge will be putting it behind him so he can focus on other problems, especially growing public favor of a Brexit, which he opposes.

-And on what many will consider a lighter note, but it really isn’t, Arianna Huffington’s Sleep Revolution College Tour begins its first full week today at Stanford and UC Berkeley. Huffington is an evangelist for sleep, and rightly so; see the item on Aetna below, for example. Sleep deprivation harms individuals, organizations, and nations, yet it’s a badge of honor at many companies and at most colleges and universities. Obviously leaders are especially susceptible. They need to get right on this issue – for their own good, and because a key element of their job is to model behavior for others.

A post-script to an item from last week: TV’s best reality show delivered once again. This year’s Masters Tournament was more emotionally draining than any in years. I have to go now. I’m still recovering.

Political Battles

Cruz stacking delegates against Trump

In often overlooked state party conventions, Ted Cruz is winning a battle that could damage Donald Trump if he doesn't win the first-ballot vote at the Republican National Convention.
