Hmm…so suggesting that black voters are unlikely to embrace Ron Paul means I think that they’re stupid? That sounds awfully like a smear. You cad. 
It’d be interesting to see a poll on what percentage of African-Americans agree with Paul’s distaste for civil rights legislation.
Meanwhile, the overwhelmingly white nature of Ron Paul’s support has drawn attention elsewhere:
*"Indeed, as diverse as Paul’s supporters may be in other ways, they are almost all white. Of the several hundred supporters at the Cranberry ¶ rally, only a half-dozen were African American.
And Paul’s seeming indifference to crises in Africa, as well as the rest of the world, may make it hard for him to attract many more in the future. Paul supports withdrawing from the United Nations and opposes not just war but any government intervention overseas – even for humanitarian purposes in places such as Darfur (he was the only Congressman to oppose the Darfur divestment act), where ethnic conflict has displaced millions of Sudanese.
His backers have picked up the theme. If you ask Chris Heit of Somerset – who wears a white “Ask me about Ron Paul” T-shirt to rallies – whether intervention is ever warranted, he’ll say, "Non-intervention is non-intervention.
“We stepped in to help end apartheid, but what did we do?” Heit asks. “South Africa is one of the most dangerous places in the world for whites.”
On the Internet, meanwhile, things can get ugly. Among the online places where you can find support for Paul, for example, is the Web site of former KKK head David Duke; one article there complained of a “Clear Media Conspiracy Against Ron Paul.” Another white-supremacy site, Stormfront.org, has numerous posts supporting Paul’s campaign, for reasons you aren’t likely to hear during a stump speech."*
As we’ve seen, Paul is not leaping to disown these supporters.
Add in the newsletter controversy and it’s tough to see how Ron Paul (assuming he ever breaks out of single digit support and has a shot at top-tier candidate status) will ever convince blacks that he’s their guy.
Once the novelty wears off, the unpleasant truths (or “smears”, as his apologists would say) about the man will make it increasingly difficult for him to get traction beyond his core nutter constituency.
