Hate to disagree, but the Left’s bubbles never burst. If the atrocities and fall of communism in the last century didn’t wake them up, nothing will.
As the author said, the true believers will go back into hiding waiting for their messiah. But the rest of the populace will learn that leftism doesn’t work at all.
So the bubbles burst for much of the population.
Those atrocities and failures were because the wrong people were trying to implement socialism/communism.
Obama was supposed to be “the one” to do it “right”. And it was supposed to work!
So, their bubble is burst on Obama being “the one to do it right”, but, as you say, they won’t give up on their utopian fantasy.
Otherwise they would have learned something from the collapse of socialism in eastern Europe, not to mention the various massacres, genocides and pogroms of communist countries.
