By Patrick J. Buchanan - Democrats are piling on Trump for cutting funding for the Centers for Disease Control and Prevention and failing to reflect the seriousness of the threat. And the issue does present a challenge to Trump’s presidency. His handling of it may determine his stature as chief executive… Yet the issue is also tailor-made for Trump… First, the disease comes out of Xi Jinping’s China, not Trump’s USA… Second, the president occupies what Theodore Roosevelt called the “bully pulpit,” the White House. He can use that pulpit daily to command the airwaves and inform, lead, unite and direct the nation during what could be a months-long crisis. And Trump alone has the power to declare a national emergency, should that be needed.
