With the pep rallies concluded, Democratic and Republican captains and their teams are charging onto the field to commence a battle for the White House unlike any other. The game plans couldn't be more different on issues like immigration, regulations and taxes, but on trade there doesn't seem to be any line of scrimmage at all. But on this one, Trump is on offense and Clinton, defense.

The latest reminder of how divided we are around the world and how poorly our political systems understand and have adapted comes this morning as British citizens voted yesterday 52% to 48% to leave the European Union. The referendum itself was the result of a risky campaign pledge Prime Minister David Cameron made in order to gain re-election. He calculated the referendum was the only way he could placate anti-EU Conservatives in his party, while holding off the growing threat that the U.K Independence Party might fracture his majority in Parliament.

Evidence is mounting that the US economy is not immune to the contagion of the global economic slowdown. The Commerce Department announced today that the US economy expanded at an anemic (seasonally adjusted) 0.7% in the fourth quarter. This compares to advances of 2% in third quarter and 3.9% in second quarter of last year. Some argue that seasonal adjustments currently used by government statisticians do not reflect the evolving economy, but it's hard to see how the economy escapes the downdrafts of global slowing, an unprecedented drop in oil prices and a surging dollar.

Can the US economy continue to plow ahead against global headwinds of the slowing economies of China, Europe and the developing world? Can it withstand the rapid devaluation of the oil industry and commodity prices? And most important of all, can it remain healthy during a period of rising interest rates?
