You can’t hope to win if you don’t understand why you lost.
Which is why I believe Hillary had no hope. She still doesn’t understand why she lost, but continues to blame it entirely on Comey, Wikileaks, and Russia. Surely Comey, Wikileaks, and Russia had some part to play, but that doesn’t explain her losing so many swing states that Obama won handidly.
As Bernie Sanders has said, to blame Comey is short-sighted. What she (and Democrats) should be looking at is why she wasn’t up by 10 percentage points or more compared to Trump. If the Democrats are content to blame racism or sexism alone, they have no chance of winning.
