No, but Raul Castro endorsed him yesterday!
If you are referring to the attempt at satire that Mr. John Semmens posted yesterday in the article Raul Castro Endorses Obama, that was in fact false. Everything from the AZ Conservative website is authored by Mr. Semmens as satire, not fact, although the content is usually based on actual news stories.
What is true is that Fidel Castro had indeed expressed his belief in the strength of a Clinton-Obama ticket back in August of 2007: Castro: Clinton-Obama ticket 'invincible'.
Mr. Semmens, could I ask you again to please label your attempts at satire more clearly? For instance, you could place in the title a comment in parentheses to the effect of "Raul Castro Endorses Obama (AZConservative Satire)".
