Who's a Republican?

Apparently, if you voted for George W. Bush, you be one.

KERRY: Are you a Republican? You answer the question. Did you vote for George Bush? Did you vote for George Bush?
UNIDENTIFIED MALE: I voted for George Bush and I...
KERRY: Thank you.
(UNIDENTIFIED MALE sits while booed by crowd) John Kerry quotes

So why is there all this angst about not accepting Colin Powell as a Republican? He usually voted for Democrat presidential candidates in the past, and voted for Barack Obama to be his president in 2008. Case closed, according to John Kerry. I think it is pretty simple. If a man's race is more important to you than his political values, he's a Democrat and so are you.
