There is CNN En Español in both XM or Sirius (that if you have Satellite Radio of course). The good thing about CNN in Spanish is that it seems "unbiased" and it is hardly like the actual CNN we listen to locally. Of course, they have news mostly from Latin America.
Also, check the BBC News Web page since it does have a Spanish section and they offer online audio en Español. I see it has like an hour news show entirely in Spanish, I don't know if is daily but i would think it is. You can check this out and the good thing is that you can listen to it whenever you want without having to follow a schedule.

Another suggestion; get iTunes and see if you can get PODCASTS in Spanish. You don't need an iPod to listen to the PODCAsts but you need to subscribe to have access to certain PODCAsts. They have several episodes of DEMOCRACY NOW! en Español!!!
Hope this helps.:hi:
