If you never learn to lose...and accept it as a part of the learning process (think participation trophies here)...then when it hits you in adulthood, it's much much harder to handle. Trump lacks the tools to handle it well, and the insight to gain them.
And another idiot who totally missed the entire point.
HINT: look up how long Gore held up the election when he lost.
Fools or just really stupid people?
Actually...stupid people keep trying to compare Trump with Gore.
With Gore it came down to ONE state, and a few HUNDRED votes. Trump is challenging MULTIPLE states, with margins well in excess of Gore's. Georgia, the tightest, is still 14,000 plus.
See the difference? Probably not.
