A Republican was trying to change a lightbulb...
...but accidentally broke it. So he got out another lightbulb and tried to install it, with the same results. He tried again, and again, and again, but every time the bulb broke in the process.
At first he thought it must have been an Obama conspiracy, but he had deliberately chosen the most inefficient lightbulbs he could find so that that Commie, Mother Nature, couldn't leech off of him.
Then he thought maybe there was a manufacturing defect, but that couldn't be the case: These were Free Market lightbulbs made by a Job Creator corporation located in the Cayman Islands for tax purposes, not some Socialist lightbulb factory laden down with regulations. So the bulbs were clearly perfect.
But why did they keep breaking when he tried to install them?
He asked his peers at the country club, and none of their ideas worked out either. Was there a lightbulb tax that was causing them to break? No, apparently not. Were they made by lazy union workers? Nope - underage foreign slave labor: The best kind. His fellow club members were at a loss to explain it.
So then he went to his pastor and asked if maybe the devil had put a curse on the lightbulbs. But after a blessing, exorcism, and big donation to the church, the lightbulbs still kept breaking.
Finally he did the unthinkable and allowed one of his blue-collar employees into his presence, and asked the man if he had any idea why the bulbs kept breaking. "Yeah, I think I do," said the man, in a bitter tone. "Lightbulbs are not like employees. You're supposed to screw them in, not over."
