Not really. Communists have always looked for an opportunity or 'excuse' to launch their revolution. Been going on for decades, long before Obama. Nothing too much new here.
From the website of the Revolutionary Communist Party (revcom.us or rwor.org) :
"Create Public Opinion, Seize Power: We are preparing minds and organizing forces for the time when there is a major crack in the system, whenever it comes and wherever it comes from: an opening that makes it possible to bring the future Revolutionary Army of the Proletariat (R.A.P.) into the field and wage a revolutionary armed struggle that actually has a chance of winning.
And we have said that building our party itself is the most important part of organizing forces for revolution. This is true now, and it is true looking forward to the creation of that future R.A.P. and the waging of that armed struggle.":

The 1992 LA/Rodney King riots were instigated by the Revolutionary Communist Party...
From David Horowitz's FrontpageMag.com /DiscoverTheNetworks.org:
"Throughout its history, one of RCP's [Revolutionary Communist Party] principal objectives has been to foment civil unrest in the United States. The most notable example of such efforts occurred on April 29, 1992, when RCP members looted and trashed the downtown and government districts of Los Angeles, triggering the infamous Rodney King riots. During the days immediately preceding the violence, RCP -- which maintained close ties to the L.A. gangs known as the Crips and the Bloods -- had circulated throughout South Central Los Angeles a leaflet featuring a statement by RCP National Spokesman Carl Dix, titled 'It's Right To Rebel' -- a quote popularized by Mao Zedong.
Encouraged by Dix, RCP activists helped lead the riots that would leave 58 people dead, more than 2,300 people injured, some 5,300 buildings burned, and $1 billion in property damaged or destroyed. On the ten-year anniversary of the rioting, RCP member Joseph Veale fondly recalled the violence as 'the most beautiful, the most heroic civil action in the history of the United States.'"
