During recent weeks the Tea Party has only received media attention when it is being compared to Occupy Wall Street, but the Tea Party continues to have an influence on politics, particularly in the Republican primary for president. The big stories around sexual harassment charges against Herman Cain, as well as that candidate's bizarre statement of fealty to the Koch brothers, for example, are also part of the story of the Tea Party.
The Democratic Party finds itself in a different situation as the sitting Democratic president is running unopposed for the nomination and already has a sufficiently enormous lead in fundraising and organization that any primary challenger who would emerge at this point would be badly defeated. The Occupy Wall Street movement is wisely not even talking about running somebody against President Obama in the Democratic Party, but this would be about the best thing that could happen to the Obama campaign. If such a candidate were to emerge, Obama could move to the center now, run up a string of impressive primary victories and use his ample resources to marginalize the Occupy Wall Street, largely through attacking the credentials and credibility of whichever flawed candidate was supported by the Occupy Wall Street. This would put him in a strong position for November especially as once he secured his nomination Obama would then be able to use his resources to again court the activist wing of the party. Additionally, running somebody against Obama would, in of itself, erode much of the Occupy Wall Street movement's support because many liberals would see the movement as seeking to destroy President Obama and behaving counter-productively.
