Only one that's possible really is North Carolina, and that would be a stretch.
She's from Oklahoma, originally. Any chance??
Yes, she wins Oklahoma. I could also see her winning Utah and Wyoming.
There is no way in the world that Elizabeth Warren, or any Democratic nominee imaginable, wins Oklahoma. Just a reminder: President Obama has never won a single county in the state of Oklahoma. While Elizabeth Warren is from Oklahoma, it is not like she is a "favorite son" of the state. She has never held elected office in the state. Democrats in Oklahoma don't have the infrastructure to win a single Congressional seat (House or Senate) and they do not hold any statewide elected office.
He was being quite sarcastic.
