[Marxism] Is there a political crisis in the US ruling class?

[Charles Brown]

<Oddly, coincidently , not only is the Republican Party split, but a
woman and a Black person are the only remaining candidates for the
Democratic Party nomination. Obama is getting a significantly large
number of white votes, a revolutionary trend in the US where
Black/White
unity is the leading revolutionary unity. The Democratic Party is a
party of big business, but these developments represents a subversion
of
the Democratic Party by working class forces.>

I would love to agree with you, but I just have to say, prove it.  
Working Class forces? Really?

CB:  Perhaps better put, critical pro-working class issues - racial and
gender unity - are forwarded  by significant advances for Black people
and women.   Breaking the barrier to an important symbolic office like
president for women and Black people would be a reform on the order of
th _Brown v Bd of Education_ Supreme Court decision.

Further, Black people are disproportionately working class in
composition, and they are voting for Obama in large numbers. So those
are direct working class forces.
