As Greenwald says:

It isn’t that difficult to keep the following two thoughts in one’s head at the same time — though it seems to be for many people:

(1) What Barack Obama is doing on Issue X is wrong, indefensible and worthy of extreme criticism;

(2) I support Barack Obama for President because he’s a better choice than John McCain.

In this case “Issue X” equals FISA, and Obama is completely wrong on the subject. I am very sorry for my friends who are just figuring out that Obama is center left at best, not a progressive angel.

Dodd, on the other hand, has it just right.
