For a short history of the governors of Bangkok this forum post at 2bangkok gives the complete list of appointed and elected governors since the merger of the provinces Phra Nakhon and Thonburi to the Bangkok Metropolis.
The election campaigns haven't made much news in the English language press, probably due to the comfortable lead of Apirak in all the polls. Only Chuwit hitting a journalist after a TV interview even made it into the German press - when I read about this incident one of my favorite quotes by Isaac Asimov came to my mind: Violence is the last refuge of the incompetent (from the book Foundation).
Leena's campaign was especially ill-fated. First she fell into the polluted Saen Saeb canal near Pratu Nam while campaigning (here's a video), and then the next day while she took a bath in another canal for a publicity stunt and one of her aides drowned.
