From the DrSanity blog:

THEY WALK THE PARTY LINE

(sung to the tune of "I Walk The Line"; with deep apologies to Johnny Cash)

I keep a close watch on those polls of mine
They're really helpful since I lack a spine
It seems to me surrendering's just fine
So when its time, I moan and whine

I find it very, very easy to change views
And when I do its always makes the News
It really is a very simple ruse
So when its time, I moan and whine

As sure as right is wrong and good is bad
Appeasing terrorism makes me glad
Because I sure don't want to make them mad
So when its time, I moan and whine

There's no way for me to stay on just one side
There are no principles to which I can subscribe
I simply float along on every tide
And when its time, I moan and whine

I keep a close watch on those polls of mine
They're really helpful since I lack a spine
It seems to me surrendering's just fine
So when its time, I moan and whine
