I think it should go:

Kelly - better at organizational task, but not willing to compromise when necessary.
Jen - not emotional, dry, willing to take credit for other's work (classic manager trait!)
Kevin - not a leader, good support guy
Sandy - too emotional, snippy, yappy

I think Sandy has a legitimate chance to go all the way though. It'll come down to her and Kevin next week.

I'd be absolutely shocked if Sandy won.

I have them ranked:
1. Kelly
2. Kevin
3. Jen
4. Sandy
