Her bio doesn't really give me much to go on, nor does her interview. She didn't really give asnwers that game me much. She says she is both devious and a likable leader, but people say that all the time and never live up to it. So who knows.
She seems to be someone with a larger than life personality. Which can make people either love having you around, or get tired of you quickly.
She seems to have good people skills, so I think she will likely make it past the merge assuming her age doesn't make her a liability in challenges. But she seems confident she can hang and without anything to base that on I will have to take her word for it.
She talks about wanting to get people to do what she wants them to do without realizing it. That is a very good skill to have in Survivor, so long as you don't do it so hard people start to figure you out. Then it becomes your demise.
Stacey gives me the vibe of someone who could sneak into the final 3 and score the win against the right other two. I.E. someone who has burned a lot of bridges.
Here is Stacey's interview from CBS's YouTube channel.
