It is time for Chris Matthews to go. His apoplectic rant against Senator Bernie Sanders and his perceived associations with Socialism, Communism is simply disgusting and devoid of fact and logic. Matthews obviously does not know the differences of the various political theories. Dictators like Castro do not practice any ideology. They are simply autocrats.
If NBC has already destroyed the evidence you can read and watch Matthews himself at this link

It is too late for Matthews to change at his age with his obvious prejudices.
It is time for Matthews to be released or retired.
