Nunes has done nothing wrong...I love how Repubs can never stand behind another Repub and fall for whatever the Dems spew.
RINO isn't just a derogatory term. Many liberals run as republicans because its the only way for them to win in the district they've targeted.
I'm not quiet sure how it could be applied, but we have a right to expect persons running under the party's imprimatur meet a minimum ideological standard.
