The leftists are Communists and Obama was raised, surrounded by and is a Communist also. They share the same goal. Destroy everything that made this country great and turn it into a Third World Communist cesspool. (ie. get rid of our history, remove god, brainwash kids in schools that Capitalism is bad, etc.)
They won't throw Obama under the bus and leave him. No way possible. The Democratic party leadership is now the Communist party. They are within striking distance of the point of no return. He (Obama) shares the goals of the leftists/anti americans/liberals/Communists/Democrats/Progressives, etc.) It is just that pesky Constitution that is getting in the way. FOR NOW.
