Which is witch?

This simple girl
From Kansas
Following
The golden road
Has never reached
The Emerald City.
Flying monkeys
And poppy fields
Stood in her way
And yet
She trekked on
Looking for a way home
Looking for
The end of the rainbow
Looking for
Scarecrow
Tinman
And Cowardly Lion.
Her faithful dog
Is her companion
But offers
No advice
Or uses any scent
To guide her
On her way.
A kindly scarecrow
Spent some time
She thought
He was the one
But alas
His straw caught fire
And he was gone.
And now
A stately Tinman
Has revealed his heart
And she hesitantly
Takes his hand
And walks the road
Again.
Traveling and
Talking with
This tender heart
Inside the
Steely frame
She reveals
Herself
Her dreams
Looks down
Not seeing
Ruby slippers
And thinks
That maybe
She is not
Dorothy
But the
Wicked Witch
After all.
