Although Alan Dershowitz is correct that candidates move to the center in the general election, his labeling of Bernie Sanders as an extremist is unfortunate (“Clinton should stand her middle ground,’’ Opinion, April 26). If Sanders is an extremist, then so was Franklin Roosevelt, as many of his time said he was.

The New Deal came about because the system had failed the average American, and that is exactly what Sanders is arguing, correctly, today. Dershowitz writes of voters wanting “evolution, not revolution.’’ Yet the only evolution that has taken place over the last three decades, with both parties, is the continual sinking of the middle class, the rise of an underclass, and ongoing wars.
