This Morning's Anagram

'Drumpf' misspell'd reads 'Dr. Fump.'
(What sort of dudes dream this stuff up?)
I spied him on a big rig's* bump-
er sticker. (In a red state? Yup!)

When re-rearranged, he's 'Mr. Pfud,'
with shades of Bugs's nemesis.
However spell'd, he's such a dud.
I wish he'd quit the premises.

* Some late mss show 'trailer's' here. 
Others show 'RV's.' All are palimpsests.
What varia have you run across?
