Who knows?
If the GOP succeeds in smearing Rice, maybe she can run for Congress in the next election, or even be appointed to some retiring Democrat's seat. She'd do great in the Intelligence Oversight Committee or the Foreign Relations Committee.
I think Liz Warren will be a much bigger headache for the Republicans now than if they had not resisted her appointment to that regulatory agency the President originally nominated her for. I see the White House in her future.
