ETA: The only thing the Republicans have done is derail Susan Rice as SoS IMO
I actually think it has made it more likely she will be Secretary of State. Her main qualification over someone like Kerry is that Obama really likes her. With everyone attacking her I think he is going to double down to defend her.
Further when it comes to a vote, the republicans are going to look like idiots for objecting to her because she repeated talking points that were either the best information the intelligence community had, or talking points that were changed by someone other than Rice herself.
I think it is very useful for Obama to be able to make the republicans look unreasonable especially over a battle he will ultimately win. That will make it easier for him in battles that he isn't in as strong of position to win because he can point to republicans unreasonableness in this case.
