If sane, Donald Trump himself cannot possibly believe the lies, exaggerations etc. he spews forth. So it must be some combination of constant need-for-attention (ref. "all press is good press"), some need to con and/or disparage people, and/or that he really has little of substance to say....Nevertheless: He's running for president/commander-in-chief: What he says and does has got to be examined:
Obama's disastrous judgment gave us ISIS, rise of Iran, and the worst economic numbers since the Great Depression!— Donald J. Trump (@realDonaldTrump) August 5, 2016
Ref.: U.S. jobs report↓ released on August 5, 2016. Off-site news article links, new windows open:
U.S. wage growth is improving but could be better, no doubt. In the huge United States the overall jobs report will rarely (if ever) be "perfect". Compare Trump's Twitter fabrication (above) though, to the actual results, news reports.....
One more 'news flash': The U.S. president cannot just wave his (tiny) hands and eradicate ISIS (etc.) from the face of the earth.
...Unless -- possibly -- you're a volatile loose-cannon, apparently ready to unleash the nukes upon provocation...
....or maybe a bit "out-of-sorts" that day....having an anger attack.....bad hair day.....just showing-off (e.g., for Putin)....etc., etc.
