It is hard to know as outside observers whether or not Bo Xilai's "leftism" was genuine. Was he cynically using nostalgia for the era of Mao and Zhou to build his own power base, or were measures mentioned as part of the Chongqing model real efforts to build an alternative to the predominant neoliberalism of the restorationists?
Although sometimes referred to as a "Maoist", his father did not support Mao's economic policies and was closer to Liu Shaoqi in that respect. And Bo appears to have distanced himself very quickly from a fledgling "Maoist" party that tried to establish links with him a couple of years ago (see my post on this: http://mike-servethepeople.blogspot.com.au/2009/11/bo-xilai-and-chinas-maoist-party.html ). Whether or not he deserved his "left" credentials he did become a rallying point for many Chinese concerned at the enormous gap between rich and poor in China. If the allegations against his wife (and by implication, against Bo) are true then the contest within the Party over the political line will have received a major setback and will have sealed the ascendancy of the restorationists.

I see it as a positive and the very first tottering step toward addressing the ever widening gap between the haves and have nots? After all, the Mainland govt is at greatest risk from its own than any outside entity or nation; and needs to urgently get its house in order, least it becomes a divided nation fighting itself in bloody internal conflict; that would suit the power hungry to their immediate east?
And, like the war of the roses, span generations.
The last thing China needs is another cultural revolution; inspired by envy and or, self serving, alleged Maoism advocates, who may see such things, whether true or simply postured, as a vehicle for achieving mostly mindless personal ambition? Rhrosty.
