Jeff Foust points out a comment by Paul Spudis at Friday's RTTM session, to the effect that people who think that the president made his announcement in January for political purposes in an election year are political ignoramuses.

I noted this myself at the time, and even named names of those ignoramuses. (Note that the article at the link says that Dwayne Day was on the Challenger Accident Investigation Board--that was a bit of brain flatulence that I've never been able to get Fox News to fix--it should read "Columbia.")
