The key sentence for me is “some cities are already leading the way”
Let Obama and HUD do this. Let the Congressional GOP enable and even support it.
It devolves the actual decision making to the local level. It forces localities to decide where their loyalties and priorities are, and the option of opting out by getting off the Federal dole.
This isn’t a bad thing. The best governance is by governments that operate closest to the people they serve and are therefore most responsive to the people they serve.
Another chapter in “the Republicans are terrified of being called racist” saga.
Had the GOP blocked this, Obama and the press would have called the GOP racist for “fighting the integration of upper middle class neighborhoods.” So, the GOP caves.
