I've been known to love me some black people.
I know that statistically, it's a very tough sell for Republicans to engage the black community because of the low-overall benefit, but I still think outreach when it doesn't endanger your candidacy is important.
As a religious minority, I am severely bothered by the lack of ethnic and religious minorities in the Republican Party.
As Matt/Beefy points out, the sad truth is that sometimes the Republican candidate can't talk to black voters effectively, because the attention it attracts will only end up exciting the core black Democratic base to turn out against you.
Now, I'm not supporting voter supression here, but I am a believer in managing public expectations and understanding the potential turnout in order to come up with a practical number of votes you need to win an election.
And especially if your candidate is a white guy running against a black candidate--sorry, It's true--you will accomplish nothing but rally your opponents against you by going after "their" voters.
I was out promoting Ron Paul tonight at a County Fair, and I didn't pass up black fair-goers any more than I did some white fair-goers. I simply discussed different things when I had their attention...primarily...the war.
And I got many positive responses that we were out campaigning for a Republican who is talking sense on foreign policy. Doesn't mean I have their votes at all, but their moral support may count at some point, or they may mention it to someone else who's interested.
