Folks have a short little memory and an infinite capacity for self-delusion.
  Trump has done nothing terrible; contrarily Bush did the War on Iraq and the War on Terror and the Great Recession occurred on his watch.
  Obama, for his part, let the whole world down like no politician ever has.
  My psychological analysis: When people feel guilty they strike out against a convenient scapegoat. The establishment has been caught and exposed with both hands in the cookie jar and they're deflecting guilt by attacking Trump.
