Bangkokians go to the polls on March 3 to elect their governor. It's a crowded field but the two leading candidates are the Pheu Thai's Pongsapat Pongcharoen, a retired Police General, and the Democrats' M.R. Sukhumbhand Paribatra, the incumbent.

Bangkok has long been the center of power for the Democrats, but Pheu Thai's Pongsapat is leading in most polls. Pheu Thai is supported by most of the Red Shirts and a Pheu Thai victory would be a seismic shift in Thai politics. The standard bearers for both parties, the Democrats former Prime Minister Abhisit Vejjajiva campaigning for Sukhumbhand on Saturday. Sunday Prime Minister Yingluck Shinawatra went on the campaign trail for Pheu Thai's Pongsapat.
