Setting up a situation that I have long expected -- a high probability of a Barack Obama-Bill Richardson ticket this fall.

New Mexico Gov. Bill Richardson, the nation's only Hispanic governor, is endorsing Sen. Barack Obama for president, calling him a "once-in-a- lifetime leader" who can unite the nation and restore America's international leadership.

Richardson, who dropped out of the Democratic race in January, is to appear with Obama on Friday at a campaign event in Portland, Ore., The Associated Press has learned.

On one level, this endorsement and the increased likelihood of an Obama-Richardson ticket is somewhat comforting -- it means that one member of an Obama Administration would actually have some foreign policy experience. But on the other hand, I don't know if the ticket would really do Obama much good among Hispanic voters -- as I've noted in the past, the general response I've heard from Hispanic students (both on the high school and college levels) regarding Bill Richardson is that they consider him to be a privileged white guy with a white name. Can that perception be overcome? And what about the betrayal of the Clinton's by this long-time Clintonoid?
