There has been practically no new housing built there in decades. The crumbling firetraps, almost all of them still owned by whites, and many by millionaires, have seen little improvement in provisions for sanitation, much less for human comfort. But per room, the rents exacted often equal many in the luxury edifices of gilded Park Avenue.

These thousands of dark-skinned people are truly displaced persons—held in a concentration camp surrounded by the barbed-wire fence of ironclad prejudice. But they attend free schools. They go to the polls. Therefore, maneuvered by slick politicians, white and black, they have become an enormous power. But little of this power is used for their benefit.

Until some 20 years ago tradition and the memory of Abe Lincoln made almost every Negro anywhere a Republican. The Republican machine in New York took this for granted and counted in the Harlem votes automatically before the elections.

A metamorphosis began with the organization of the American Labor party and the growth of the Communist party. These radical groups were weak and poor. They had no hope of electing anyone, and therefore could promise anything to everyone. Negroes, who had nothing to lose, began to be attracted.

For the first time they found themselves wanted, courted, flattered.

The Republicans suddenly woke up to find Harlem slipping away. They joined the parade, and held out new big promises of patronage. They suddenly grew conscious of social obligations, too, a new line for the G.O.P.

Everyone hopped the bandwagon in this new crusade—for the Negro vote. But the Negroes had been inflamed over their grievances and preferred to nurse them, now that self-seekers had acknowledged and emphasized them. Besides, the Republican party never won local elections anyway.

On the crest of this wave rose a shrewd little opportunist named Fiorello H. LaGuardia. He took over Harlem as a private preserve with a fusion of both the Republican and A.L.P. bodies of New York. After he was elected mayor, he sent to Congress, to succeed him from the fringe of Harlem, one Vito Marcantonio, a stooge who had worked in his law office.

With Marcantonio the local leader (State Chairman of the A.L.P.) and LaGuardia for a round dozen years in the City Hall, the pay-off began. The unfortunate Negroes, who had been cuffed and confined so long, were suddenly silk-gloved and pampered, made virtually immune from the police and the law. In this tight little empire ruled by the LaGuardia-Marcantonio axis, everything went, short of, and sometimes including, murder in the first degree.

Harlem, which had once been notoriously frustrated, now sprang into a peculiarly privileged status in reference to the city's laws.
