The remembrances and celebrations of this anniversary mostly took place over the weekend, where people gathered on the Mall in Washington to celebrate Dr. Martin Luther King Jr’s speech, life, and cause. Today is the actual 50th anniversary of the “I Have a Dream” speech, which will be commemorated again today in Washington. CNN’s Don Lemon previews Barack Obama’s remarks:

We certainly have come a long way since 1963. Would Dr. King be satisfied?  I suspect not, but his dissatisfaction would probably be across a broad number of issues, and not just limited to civil rights.  Rep. John Lewis (D-GA)’s more positive take is closer to the truth, I think.  We have changed greatly as a nation on the question of equality, and for the better.  We have eliminated government-imposed discrimination and boosted enfranchisement to parity levels.  These days, we have to ask whether government intervention — which undeniably drove those positive changes in the first years after this speech — has become more of an obstacle to progress, especially as it relates to education and economic opportunities.  On those scores, I’d guess that Dr. King might find his greatest disappointments.
