Why do Republicans constantly complain?

I remember during the Clinton years they would whine about the president and come up with any reason to impeach to him.  It made watching politics a pointless exercise in listening to old people whining, along with the unending jibberjabber of talk radio that only serves to make listeners paranoid as they succumb to the same holier than thou thought process.  I learned more about politics watching Duck Tales.

The fact of the matter is, the Republicans ran a horrible, HORRIBLE campaign this election. I mean come on, Joe the plumber? And they ran with it? They have no reason to whine. While they were in the whitehouse they had absolutely zero tolerance for any bi-partisanship, for example Alberto Gonzales, stem-cell research and abortions. Yet now that we will soon have a new president they are already screeching about the Democrats being 'unfair' and partisan. It's sickening.
