Iowa is really important, at least if you're winning.

So, Iowa’s important, I suppose,
So long as you can win it.  If you don’t,
And you’ve defection in the camps, you won’t
Imply that it’s the very state you chose
To highlight your electability.
But if you have a surging in the polls,
It’s likely all your previous cajoles
To Democrats, or racist nuttery,
Or any other awful thing you’ve done
Or said will be evaluated, scored,
Used to excoriate you, then ignored
When someone else is rising like the sun
In Iowa.  Contestants, feel no sorrow,
For someone else will take your shame tomorrow.
