I am excited to see the U.S. take a historic stance and break down the racial barrier to the presidency. It was in 1870 that the 15th Amendment to the Constitution was passed - the amendment that made it illegal to bar someone from voting based on their race.
Now only one barrier is left - the gender barrier. It took fifty years after the passage of the 15th Amendment for the 19th Amendment to be passed. This was the amendment that allowed women to vote -- black and white women. I don't want to turn my eyes to the future too soon, but I sure hope it doesn't take another fifty years before the first woman attains the presidency.
