False premise
Incommensurabilities
Pretzel logic
Palin is backing(every day on the radio) the most powerful and evil RINO in the Republican Party.
Therefore, Palin is a RINO.
Considering she supported McCain for President in 2008, that McCain campaigned for her, and that the "RINO" Palin is today campaigning with her, it would seem that Michele must be "purged."
Seriously, "RINO" is the last adjective I'd attach to Bachmann (or Palin, for that matter.)
