I've tried to be fair in assessing policy — but Trump policy is baffling. Researchers at NBC News have cataloged his positions on major issues since the start of the campaign. They have found 19 different positions on immigration reform; 15 different positions on banning Muslims; nine different positions on how to defeat the Islamic State group; eight different positions on raising the minimum wage; seven different tax plans; and eight different strategies for dealing with the national debt. And the more or less consistent persistent positions are the scariest — more nukes and denigration of the president of the United States coupled with admiration for the Russian dictator.
