Richardson Endorsement

Despite what Clinton's campaign might say, Bill Richardson's endorsement of Obama is huge.  Richardson is a western, somewhat libertarian democrat (an example would be his pro-gun views).  Last year, he was the one democrat I was really pulling for.

Richardson is also of hispanic descent (though not an immigrant himself).  He speaks Spanish fluently and will likely help Obama in that segment of the population.  

Furthermore, Richardson is a very close friend of the Clintons and worked in their administration.  While he had never endorsed Clinton, it seems that this is just another nail in Hillary's political coffin.
