Katrina Diaspora--A Boon to Obama??

Today's Washington Post has an article about the displaced population of New Orleans, much of which relocated to Texas. The question this article raises, and which is almost impossible to answer now given the lack of available data, is how the several hundred thousand new Texans will affect next week's Texas primary. At first glance this would seem to bode well for Obama given the demographics of this population--overwhelmingly African American. Nonetheless, until we get some hard numbers next week we won't know for sure. Even then, we'll have to do some pretty intense number crunching, I would think, to conclude anything definitively. Anyhow, it will be worth watching Houston and Dallas returns especially.
