RINO is an acronym for Republican In Name Only, and is often used to describe a Republican politician who is believed to be more aligned with the values of the Democratic party. Some synonyms for RINO include moderate Republican, liberal Republican, or centrist Republican. These terms all suggest that the politician in question does not adhere strictly to the conservative principles that are traditionally associated with the Republican party. Other terms that are sometimes used to describe RINOs include turncoat, traitor, or fake conservative. These more negative connotations reflect the frustration and disappointment that some Republicans feel towards politicians who they believe are not true to their party's ideals.
