@Builder,
She was a republican when she was in college in the late sixties for Christ's sake. It's not a lifetime commitment, you can even change your voter registration if you become disenchanted with your party.
DINO is a term Lashout like to toss around, no one else uses it. When republicans decide another republican isn't as pure a republican as they are, they label them RINO's. (Republican in Name Only). The uber-conservatives watch each other like Hawks to make sure everyone thinks and speaks the same appropriate republican way.
That being said, there is a big difference between regular republicans and the radicalized republicans.
