I had also thought about Mr. Gaeta and to be honest am split between him and Tom Zarek. What makes me decide on Zarek is the fact that he is the Vice President. I think the end game plan of the cylons is to take over and integrate without humans even knowing it. Right now (if I am correct) the second in charge in both Military and Government would be a cylon. And we know Roslin is dying. One down, one to go.
