I don't see how the party can expect to be taken seriously if they back out now. To be honest, I always felt her addition to the ballot was just a ploy by the Repubicans to diversify... (to make themselves look as progressive as a black candidate).
Regardless... Presidents & VPs have always been party hand puppets. Somebody simply dropped the ball by not scripting her speaches/interviews properly, and letting her improv.
....Light travels faster than sound. That's why some people appear bright until you hear them speak.
