Clearly, for Sukhumbhand to rally back and win (if the polls accurately reflect reality), he will have to convince most of the remaining undecided voters to vote for him, or something would have to go terribly wrong for Pongsapat. Outside of this, he would need to strike some kind of bargain with other candidates to get their voters to vote for him.
There could also be an X factor - In the 2011 general election, Puea Thai scored well in exit polling, showing they would secure 25 seats and the Democrats 8. However, after the ballots were counted, the Democrats took 23 seats and Puea Thai only 10. How did this happen? You can imagine with such a major turn in events from the exit polling to the final results a number of theories emerged to explain this...
