I just read the transcript of the press conference after reading such discussions on DU as

KUDOS to President Obama for pushing back on the unappreciative left. . .

After reading it all, it was this very short exchange that illuminated it all

With respect to the bottom line in terms of what my core principles are —

Q Where is your line in the sand?

THE PRESIDENT: Well, look, I’ve got a whole bunch of lines in the sand.

I guess he doesn’t even get the concept of core, or line in the sand.

FYI, for people who have principles, THERE’S  ONLY ONE OF THEM.

Not a bunch. Making taxes for the rich temporary is the same “line in the sand  W had. And this was the last chance to get rid of them.

Obama has no core. No line. Just a bunch of caves.
