WASHINGTON (AP) — Call it the campaign trail shtick.
Have you heard the one about the kid who thinks President Barack Obama's job is to "approve this message?" Or the time Mitt Romney compared another presidential run to giving birth?
The jokes at presidential fundraisers and rallies are easy applause lines for Obama and Romney. They're a way to entertain supporters before the talk turns to more weighty subjects like Medicare, taxes and foreign policy.
A good sense of humor has served presidential candidates well in the past so it's little wonder why both Obama and Romney are using the technique.
