Today, delegates to the Republican Party's National Convention behave like this:
An attendee to the US Republican party convention was removed from the conference after allegedly throwing nuts at a black camerawoman from CNN, saying "this is how we feed animals".
and like this - towards members of their own party, apparently for being, well, Latina:
Not to worry you, but the gap between the candidates is currently 1%. I'm not that bothered that Mitt Romney wears special religious underpants and believes that Jesus visited America. I am bothered that his party hates women, believes weird things about their biology, promotes the most vicious forms of capitalism, thinks it's OK that a Presidential candidate keeps his millions in the Cayman Islands, Switzerland etc - he wants to run the government, not contribute to its maintenance - and believes that electing representatives whose faces contort with racial hatred is apparently fine.
(Puerto Rico was seized by the US at the end of the Spanish-American war. It's a dependent territory, essentially an offshore possession in which citizens can't vote for the Presidency but do have an elected governor).
