Kenny Polkari: On this 4th of July, I'm grateful for an America that is colorblind. Starting in 1896, Justice John Marshall Harlan observed that our Constitution is colorblind and neither knows nor tolerates classes among citizens. In just a few days, the Supreme Court has determined that yes, it will remain faithful to the promises of a colorblind Constitution and Declaration of Independence. This is Sarah Perry, senior legal fellow at the Heritage Foundation.
