No, that's not the same kind of thinking that got us an Obama. In this case, in order to impose the death penalty, Texas jurors must find that the defendant will likely commit future violent crimes. Race is (or should be) irrelevant to that determination, because the issue is whether one particular defendant will commit future crimes, not whether blacks as a race are likely to commit future crimes. So, allowing race to be a consideration is improper, and not at all race-blind.
In the case of Obama, his election was the precise opposite of race-blind. America didn't elect Obama with no consideration of his race, America elected Obama because of his race.
Well said.
I think the definite lesson in this case is that the prosecution, in future, should avoid making a case based on race.
