I received a pm asking me what I meant by the phrase "racial code words".

"...racial code words are words politicians (usually Republicans) are accused of using to supposedly help them win votes by raising whites' fears of minorities. According to pundit Clarence Page, racial code words include terms like "states' rights," "crime in the streets," and "welfare queens."

Racial code words refer to stereotypes about a specific group, and are often stated indirectly. Other referents for using "racial are "playing the race card", "race baiting", or using "racial innuendos."

Here's an example of Hillary Clinton campaign's use of "racial coding":
Bill Sheehen's expression of concern that if Barack Obama becomes the Democratic nominee, the Republicans would bring up the fact that he used drugs and the Republicans would question if he {Obama} ever sold drugs.
{Note Obama experimented with marijuana and cocaine as a teenager and never sold drugs. Other politicians-including Clinton have admitted to using drugs. However rarely if ever have they been accused of selling drugs. This "concern" fits into the "Black men as drug dealer steeootype.

The most recent example of the use of racial code words by the Clinton team is use of the phrase "shucking and jiving" to describe Hillary's competitors campaigns. See this Jan 10, 2008 article entitled "Racial code words rear their ugly head?"

"I've been pretty familiar with New York Attorney General Andrew Cuomo's work for quite some time, so I'm willing to extend some benefit of the doubt here, but this was certainly a poor choice of words.

A big Hillary Clinton supporter and statewide official in New York might have just given the Hillary campaign a real headache. During an appearance yesterday on talk radio — at almost the same time as Obama co-chair Jesse Jackson Jr. questioned Hillary's tears — New York Attorney General Andrew Cuomo used some words with a very troublesome racial history, apparently in reference to Barack Obama.

"It's not a TV crazed race. Frankly you can't buy your way into it," Cuomo said, according to Albany Times Union reporter Rick Karlin. He then added, "You can't shuck and jive at a press conference. All those moves you can make with the press don't work when you're in someone's living room."

Because the phrase "shuck and jive" has a racial background, Cuomo was speaking on Clinton's behalf, and Obama is Clinton's principal rival, the comments raised a few eyebrows..."

That article also links to a recent article by Karl Rove that is full of racially charged language. Here's an excerpt of that article:

"...in the course of a single column Rove manages to flag Obama's "trash talking", "his days playing pickup basketball at Harvard", and the alleged fact that "he is often lazy." "

See this poster's comment from a dailykos diary:

"It is more than Cuomo's comments, it is a growing number of moments where those associated with the Clinton campaign (formally/informally) have dropped racially tinged innuendos. This is becoming more than a series of dis-associated accidents. Are the Clinton's racists? I can't answer that. I haven't looked into their hearts. Are they playing to the racial insecurities/fears/prejudices of many Americans? Yes. Is that racist behaviour? You make the call."

See also this comment from a poster to that dailykos diary combines a number of the racial innuendos that the Clintons or their campaign staff and spokespeople have used to refer to Barack Obama:

"Give me a break, this whole thing is just a fairy tale. The Clintons are just shucking and jiving about their invisible hip black friend who is busy selling powder (or was it crack) at his local madrassa."

Also, see this excerpt from another dailykos diary:

"...Day after day we have seen the racially charged comments from Clinton aides, endorsers, and even President and Mrs. Clinton themselves. They have been extremely clever, delivered in such a way so that there is plausible deniability (especially in the cases of the Clintons) or where there are no Clinton fingerprints, the classic delivery method of a swiftboat attack."

The Swiftboating of Barack Obama

There's a number of other examples that could be cited when Hillary Clinton used racial code words. The latest one I read about online is this one:

RUSH: Did you hear what Mrs. Clinton said on the Today show today with Matt Lauer? She said that Barack Obama "hasn't done the spadework necessary to be president."

...Now, let's imagine, shall we, if Trent Lott or Mitt Romney or Ross Perot had said that Barack Obama "hasn't done the spadework necessary to be president." Nothing that happens in the Clinton campaign is coincidence, folks. Barack Obama hasn't done the "spadework"?

-snip-

In this instance, the racial code word is "spade" which has been used as an informal reference for Black people.

What could be the reason for these uses of racial codes?
I believe these codes are purposely used to inject "race" in the campaign and to reinforce the view that some people have that a Black person should not be President of the USA.
