'Nellie The Elephant' Decoded

Annotations in italics, anagrams underlined

To Bombay 

(by Obama; bye bye Obama, to replace Obama)
A travelling circus came 

(circus is the satanic circus, a sham)
They brought an intelligent elephant 

(donkey; dumb monkey, role reversal)
And Nellie was her name

(Nelly is nearly nearly, as a Donkey is nearly(near to) an Elephant in US politics)
One dark night
She slipped her iron chain
And off she ran to Hindustan 

('Trump loves Hindu..' Stan is abbreviation for Satan, he's not going to Hindustan (He's not the one who leaves),ran as in ran for office, or could mean became a Hindu, ran to Hinduism)
And was never seen again 

(Fell off a clint(cliff), off is on)
Nellie the Elephant packed her trunk 

(trunk as metaphor for penis/willy/Billy Clinton)
And said goodbye to the circus
Off she went with a trumpety-trump 

(petty complaints about D(evil) Trump)
Trump, trump, trump 

(...more complaints, possibly about dicks/men)
Nellie the Elephant packed her trunk
And trundled back to the jungle
Off she went with a trumpety-trump
Trump, trump, trump 

(3 word campaign slogan, such as Drain The Swamp, Lock Her Up)
Night by night
She danced to the circus band
When Nellie was leading the big parade
She looked so proud and grand 

(gay parade; gay pride,agenda)
No more tricks
For Nellie to perform 

(destitute presstitute prostitute)
They taught her how to take a bow 

(to bow out, leave the stage)
And she took the crowd by storm 

(insults her supporters? A 'final' calamity, yet to come?)

Nellie the Elephant packed her trunk
And said goodbye to the circus
Off she went with a trumpety-trump
Trump, trump, trump
Nellie the Elephant packed her trunk
And trundled back to the jungle
Off she went with a trumpety-trump
Trump, trump, trump

The head of the herd was calling
Far, far away
They met one night in the silver light 

('Ever Dance With The Devil In The Pale Moon Light?')
On the road to Mandalay 

(dalay~=delay the Man, her mission)
Nellie the Elephant packed her trunk
And said goodbye to the circus
Off she went with a trumpety-trump
Trump, trump, trump

Nellie the Elephant packed her trunk
And trundled back to the jungle
Off she went with a trumpety-trump
Trump, trump, trump

Nellie the Elephant packed her trunk
And said goodbye to the circus
Off she went with a trumpety-trump
Trump, trump, trump
Nellie the Elephant packed her trunk
And trundled back to the jungle
Off she went with a trumpety-trump
Trump, trump, trump
