The minority stuff is a second issue that some folks seem to be getting confused. The 47% speech is from back in May, and as many have pointed out Gov Romney said nothing about race in that speech.
Where the OTHER part is coming from is a "joke" he told just a few nights ago:

I don't know if anyone cares about this comment or not, just thought I'd post it to clarify where (I think) some of the confusion was coming from....
