The Communist Party of America as reported in People's World is endorsing the Democrats in the next election. While they do have criticisms of Obama, they are supporting the Democrats against the "right-winged extremism" of the Republicans.
Further, they add:
We are keenly aware of the fact that the agenda of the far right is to bring this administration and country to its knees, with a heavy dose of racism, lies and economic sabotage, setting the stage for a full blown return to power of the most reactionary, racist, anti-labor, anti-women, homophobic and militarist grouping in U.S. politics.
Yep, and they support Obama, or course.
