1. Significant stock market drop, which will usually precipitate a recession. The party in control of the White House usually doesn't win reelection. Look at 2008, 2000, 1992, 1980. The best way to indicate a future recession is the bond market. It is the most impartial indicator out there. Look at the yield curve, more specifically a flat yield curve, which moves to an inverted curve. Now that I say that, Janet Yellen has fucked up the most pure and logical way to look at the future health of the economy.
2. A significant terrorist act. No, Istanbul doesn't count.Meanwhile the stock market is leveling off, Benghazi reports don't look good for Killary, and yet another terrorist attack that libs can't blame on guns.
Donald Trump's speech today had the first coherent & significant language that he has spoken for more than a year, & of course we all know someone ells must have written it.
& if you are the Donald you have even less to work with under the haystack.
