Imaginary Barack was invented in Hawaii, sneaked into the Oval Office, and has no legitimate claim on the presidency. As for the real tall black guy posing in Washington, go ahead and treat him any way you want. You can jab your finger in his face, shout him down, call him a Muslim, a Kenyan, an illegal alien, you can invent all kinds of lies about him and then you can tell him – get out of that chair.
In reality, the president is a more-or-less mainstream, smarter-than-average pol, left-of-center on some things, to the right on others, like guns, disturbingly hawkish on ordering the killing of American citizens suspected of terrorism, on national security, executive secrecy and immigration. He is, too, an inveterate compromiser who used to bend over backward to make deals — sometimes in advance! — with Republicans.
