I'll grant that it can be painful to have the smug ripped out of one's psyche like an infected molar without novocaine. They assumed and continue to assume that there is only one way for intelligent people to think and if someone doesn't think that way, it's because they're stupid. While this may confer a certain emotional consolation it doesn't advance anyone's education very much, and when their standard-bearer pens an explanatory volume entitled "What Happened" it might as well have a question mark appended. They've learned nothing. It's too hard. Anger and outrage is easier.
What actually happened was not a sudden plunge into an alternate dimension or the death of a close relative with the concomitant stages of grief that are currently a principal feature of the evening's television banquet. They lost an election. Deal with it.
We have seen a flurry of stories that indicate that the working-class wipeout did get the Dems' attention too late. But once again, nothing was learned and the general consensus is that the working class - wait for it - is too stupid to know the working class's interests. Somebody certainly is, but it isn't the working class.
