One has to be mindful of undecided voters. They can create surprises.
When a survey was conducted a few months ago the indication was that 40 percent of the electorate were undecided. This percentage is quite high. How are these voters going to vote? There is no recent survey or opinion poll, subsequent to this, to give any indication of how voters are going to vote and we have to wait for the actual polls on 4th December, not the size of the crowd.
