"Has anyone noticed how much Obama sounds like M.L. King Jr?"

His preacher style rhythm is certainly modelled on Dr. King but the substance isn't there. He also tones it down a bit with regards to pitch.
Note his most recent ads which include black & white footage of himself, JFK & MLK. Voiced over by Teddy Kennedy & approved by Obama.
Both of those men had vision and were able to impart that vision even to us, as children outside of the USA.
He manages to say that he has plans to help the poor but doesn't say what those plans include.
He says he wants health insurance for all but comes up with a plan for those who can afford it.
These are motivational speeches which seem to work well within your own culture but come across as hollow & insincere to many nationalities outside of the U.S.
In the meantime, with the exception of blacks & students, his votes & donations are coming from the higher income brackets while the poor are voting for Hillary.
The latter a quote from one of the other networks, last night.

Amos: Yes they are leaps but looking at the inevitable.
Hillary Clinton and the people of Michigan, Wyoming & Florida (is there one more?) all have it in their interest to see that their votes are counted. That is how democracy works.
To ignore millions of votes which could change the outcome of a race would be political suicide for the Democrats.
In a general election, they would stay home in droves.
