Alan Grayson, Leftist Bomb Thrower from Florida, wants the president's press secretary fired after his criticism of the "professional left."
By having a fight with the Loony Left, the White House creates the illusion that it is something other than the Loony Left. By having a fight with Gibbs, Grayson excites his Loony Left base. Politics as usual.
Gibbs is simply following the script that the White House wants him to. Grayson might as well call for the president's resignation. Hey, that's not a bad idea!
