Being a guy who works long hours on the weekend, I didn't have time to address Bernie Sanders' Netroots Nation kerfuffle, so ably covered by Tengrain, who also ably covered the ensuing media freakout.
Personally, I consider myself a liberal, not a Democrat per se, and that the "Black Lives Matter" protestors were present to ensure that the primary concern of the African-American community, typically a solidly Democratic voting block, is addressed by the Democratic presidential candidates. I've read some website comments taking them to task for putting Bernie Sanders, who has a 97% rating from the NAACP, on the spot, but they are literally fighting for the lives of their loved ones. At the very least, Bernie should have been better able to extemporize a response, even if it were merely a promise to listen. Bernie's a prickly old Brooklyn boy, and he was thrown off his game by an unexpected confrontation.
Class matters to the African-American community, it has since the first African slaves disembarked in the British colony of Jamestown in 1619. African-Americans have always been the canary in the economic coalmine, the first to suffer in times of privation. Class issues, though, currently take a backseat to the problem of systemic racism, particularly in the death of African-Americans at the hands of law enforcement authorities.
Bernie should appoint an African-American advisor to coach him on issues of concern to the black community- the population of Vermont is over 95% white, so Bernie needs to improve his ability to communicate effectively to minority voters.
In the meantime, the media response to Bernie's gaffe was absolutely atrocious, with Ruth Marcus taking the prize for being stupid and obnoxious:
It's obvious that Ms Marcus doesn't consider African-Americans, who are concerned with the appalling death toll in their community, are "normal voters", let's hope that Bernie doesn't make that mistake... we need the guy in the race to ensure that economic justice remains an issue in the upcoming election.
