Obama and Affordable Housing
I think Ezra's giving short shrift to Barack Obama's housing policy commitments. It's true that, as for every president, affordable housing issues aren't going to be priority number one in the Obama administration. But his support for creating an Affordable Housing Trust Fund isn't just boilerplate, this is actual legislation that's a top priority for affordable housing advocates.
Note, conversely, that programs conservatives claim to believe in like Section 8 housing vouchers suffered a lot under the GOP congress and would suffer much, much, much more under John McCain's proposed cutbacks of domestic discretionary spending.
