"Why is the economy slowing? The usual suspects wasted no time blaming President Obama. But you need to remember that these same people have been warning of imminent disaster ever since Mr. Obama was elected, and have been wrong every step of the way. They predicted soaring interest rates and soaring inflation; neither happened. They declared that the Affordable Care Act would be a huge job-killer; the years after the act went into full effect were marked by the best private-sector job creation since the 1990s."-- Pundit Paul Krugman, June 6, 2016.
Comment: This is ad hominem reasoning. Yes, many of Obama’s critics have made false predictions about Obama’s policies. But that doesn’t mean that they’re wrong now. After all, Obama and his supporters have made false predictions and been wrong from time to time, as well; the fact that they were wrong in the past doesn’t guarantee that they’re wrong now. Also, is it really true that Obama’s critics have been wrong “every step of the way”? Not once have they ever made an accurate criticism of Obama? That sounds like a distortion.
