Well, come on, it's crossed everybody's mind. Obama himself talked about discussing it with Michelle before agreeing to run; they know exactly what they're facing. But that's no reason to dwell on it. Every American president takes that risk. You don't have to be black to have the threat cross your mind; there are all varieties of crazy people with enough violence and hate. Reagan, Kennedy, McKinley, Lincoln - they were all white men, and it didn't protect them from nutters.
This stuff will only get as ugly as we let it. Stare it down - it's crap, always was.
We'll live. Everyone who's a first anything has a tough road. Just today I was reading some of the stuff Susan B. Anthony got called in the media during her lifetime. Ouch! Glad it didn't stop her, though.
This is my prediction, and I really, really hope I'm wrong: if Obama is elected, he will be assassinated.
I don't know... there's a TON of people out there the KKK and their ilk would love to get rid of. And they're all walking around without even the benefit of one of the world's most highly trained staff of personal bodyguards.
