This is not based on any proper analysis at all but I get a feeling that there weren't that many really close marginal seats in this election. Is that just my imagination?
You are right, out of 543 seats, 95 were won by a margin of 5% or less. In 2009 196 seats were won by a margin of 5% of less and in 2004 151 were won by a margin of 5% of less.
Any idea why? Because of BJP overreach in it's good areas?
Also, looking at Al's great list it's kind of striking how much this was an INC loss. They lost seats all over the place, not just to BJP. On that note, the polls seem to have predicted BJP more accurately, while INC ended up doing even worse than the polls showed, no? I remember the talk as being about "omg, INC may actually drop into double digits" and then they fell to like half of that in the election.
