It should be self-evident that both the Republican and Democratic parties represent the interests of the capitalist class in every imaginable way.
Their funding comes almost exclusively from corporations and they themselves are members of the wealthy elite.
There are differences, to be sure, which are not insignificant, but it is important to first tackle some major questions:
Why have two corporate parties dominated electoral politics for most of this century?
Why do liberals have so much trouble keeping up in electoral politics?
How has a system which works against the interests of nearly everyone subject to it stayed in place for so long?
These dilemmas come into sharper focus if we realize that many liberals and intellectuals who consider themselves to be 'left' are still under the sway of election ideology, even more so than “ordinary” Americans, and that it is necessary to abandon our view of elections as simply a political tool.
It is possible that elections be used as a means of representation in a democratic system, but means of representation and democratic systems are not relevant to American capitalism.
An election in American society is not a political tool but an Ideological State Apparatus.
