She could've been a contender.
But I think this is a bad move on her part. She's got the looks and personality to make it to the White House, but lacks the experience to make more people want to vote for her. IMO, she should stay on as governor and get more experience as an executive. She should also immerse herself in geopolitics to gain the understanding and expertise needed to debate political rivals on the national level. I'm afraid this move is a dead end for her.
