The recent racial/gender spat between Barack Obama and Hilary Clinton may well determine who wins the nomination.
However, when it comes to independents - I bet they just lost the general to McCain, should the Republican's be wise enough to nominate him.
Time will tell of course, and there is still a long ways to go till the election. Barack and Hillary are certainly not above 'Atonement', but it's gonna take more than just words.
