“would it be beyond Russia or...to stir up racial divide.”
I believe you are right. Starting almost 2 years ago, moderate left/environmental parties were being infiltrated by far left parties like the Party for Socialism and Liberation. The PSL had split off from the Workers World Party over tactical differences, and the WWP had supported the Soviet invasion of Hungary, approved the Chinese attack at Tien An Men Square, and sympathized with North Korea. Far left marxist/socialist parties like the PSL and others have never been able to win enough votes to gain ballot status, so they invade more moderate left parties like the Green Party that do have ballot status to push their agenda. I believe the west coast dock workers strikes are connected to this as well.

Additionally, a Soros funded foundation has spent 33 million dollars in support of Ferguson protestors/coalitions.
I’m pretty sure Commies and Commie sympathizers are trying again to start a race war, using the same old tactics for toppling governments that they have used successfully on other nations.
