"If you don't mind me asking a question, Will the "Halperin Memo" come back to haunt ABC news & Mark Halperin?"
It won't affect his standing within ABC, but he will never get a pass from Republicans/conservatives from now on. His memo will serve as a talking point as well for Rush, Hannity, Fox, etc.
Point given. But I don't think it will stop ABC from putting him back in the stable, sort of speaking.
