Nobody like that 'round here

A word used to describe a fallen from grace politician from Texas sent me scrambling for the online dictionaries yesterday. Here's what I found:
Hypocritically, complacently, or effusively earnest
Unpleasantly and insincerely flattering, friendly, or groveling
Unpleasantly and excessively suave or ingratiating in manner or speech
Buttery, fulsome, oily, oleaginous, unctuous?

Smarmy?
