Johnson's escalation of the Vietnam War ruined much of his credibility as President. Johnson was wary of potential political attacks from the right for losing a portion of the world to communism.(Wikipedia, LBJ). Obama now holds the same compass in his hand.
Obama was given the choice of two compasses, one pointing towards a return to peace and prosperity at home where it has been needed for a decade, the other one the "W" compass.
In a Diane Sawyer interview he recently said "I would rather be a really good one-term president, than a mediocre two-term president", indicating he can't get enough of those sugar crisps (ideological notions).
Then he set out to freeze the economy that helps the middle class and poor the most, leaving the military oil media complex budget at its fattest ever.
Not gonna be a good one term president nor a mediocre two term president using the "W" compass dude.
If you are so dead set on bringing the presidency down, the least you can do is not drag the many legitimate democrats, who do not like this compass, down with you.
