Because "malarkey" is his favorite word. He just loves it.
On Sarah Palin's negative attacks on Obama: "It's just malarkey, flat malarkey."
On soothing Virginian voters on the right to bear arms: "I guarantee you Barack Obama ain't taking my shotguns, so don't buy that malarkey."
On one of Bush's speeches in Israel: "This is bullshit, this is malarkey."
Malarkey! Tee-hee. The word makes me giggle. An image of a nineteenth-century southern gentleman comes to my mind who uses malarkey in the same sentence as carpetbagging and gerrymandering. Or a rotund politician, circa 1920, dressed in an ill-fitted black suit and decrying his involvement in the Teapot Dome scandal.
Tee-hee-hee.
