Since the WSWS

thinks there's not a dime's worth of difference between the Democratic and Republican parties, why in the world would there be any infighting at all of the Democrats?

I like this part:

Obama’s mind-numbing platitudes—his empty slogans of “hope” and “change” and invocations of the “American Dream”—cannot address the profound contradictions of American capitalism and the crises that beset it both at home and abroad. There is, moreover, the danger, from the standpoint of the ruling elite, that his candidacy could unwittingly serve as a catalyst in the political radicalization of broad masses of working people and youth.

Should Obama, as seems increasingly likely, emerge as the Democratic presidential candidate, the divisions within the Democratic Party establishment will remain and the stage will be set for a general election that could sharply polarize the population.

Mind-numbing is right.
