Oh dear, oh dear!

What's with Nigel Farage?  Up until now, as far as I am concerned, he's been an amiable buffoon - good for a laugh with some way-out ideas, but essentially good-natured.  But now it seems he's turned into a Donald Trump Mini-Me.  His recent rant against Obama where he described him as "a loathsome individual" was most un-Farage-like.  So the question is - was he always like that beneath the surface, or is he simply seeking to hitch a lift on the Trump wagon?  I sincerely hope it's the latter and only temporary.
