Krugman, a typical leftist moron that mistakenly 'thinks' that he is smarter than anyone.... while making patently false tweets like this one "Republican belief in the growth magic of tax cuts is the ultimate policy zombie". Tax cuts have proven to spur the economy and increase revenue, vs. the Democrat ssdd 'targeted tax cuts' and war against the "rich". Yet this "professor of economics" is too dishonest, being a leftie, to speak the truth. If he really wakes up each morning to dread existence, he might want to look in a mirror for the very valid reason.
