Time to grow up

Are you as tired of all the political bickering as I am? Am I the only one who thinks that the name calling and the lines being drawn in the sand are counter-productive?
We have elected leaders who think it's OK to hold the country hostage because their particular state did not get the pork they want [Shelby]. Or Senators who say one thing one year and then conveniently forget what they said and claim the exact opposite a few years later when asked the same question. Hello? We have a thing called video files now. We know what you said and we can play it to show you up [McCain].
Or political aspirants who cowtow to a radio talk show host and say it's OK for him to say something derogatory but not someone else because it's politically expedient [Palin].
The one common theme here is that these are all Republicans. I'm sure I could find Democrats who are guilty of similar things but right now the GOP is on my last nerve. Regardless of what party they belong to, politicians are there to serve this country, not their own political agenda.
Grow up already and do your job.
