To the Editor:

Re “You Must Never Vote for Bloomberg” (column, Nov. 11 ):

Charles M. Blow’s diatribe against Michael R. Bloomberg is a perfect example of why American progressives almost never succeed in electing anybody.

At the end of three terms of Mr. Bloomberg’s mayoralty in New York City, The New York Times said: “The crime rate is down, the transportation system is more efficient, the environment is cleaner.” All good reasons for people of any color to consider his candidacy for president.

And I largely agree with Mr. Blow’s opposition to stop-and-frisk, but it was not a “terror campaign” against young black and Hispanic men; it was an overreaction to gun violence, which, like mandatory sentencing for drug offenses, had racist consequences that were not anticipated when the program was begun.

Please, progressives, do the electoral math: If you take all those who wouldn’t vote for Elizabeth Warren because of “Medicare for all,” and all those who wouldn’t vote for Pete Buttigieg because he’s gay, and add those who wouldn’t vote for Mr. Bloomberg because of stop-and-frisk, your sum is likely a Trump victory.
