AAP fellows are truly delusional - their leader predicted a 100 seats in the Lok Sabha, and their official website predicted 300. They ended up with 4.
Kejriwal is wrong about winning a 100 seats | Aam Aadmi Party
Naive about politics is an understatement in their case - any layman could have told them that such numbers belonged to the realm of delusional fantasies, not electoral reality. But they thought that holding dharnas and criticising everybody, without themselves being able to do anything, would keep getting them support.
Look at what is happening in Delhi now - AAP got a golden opportunity to make a difference there, and to show people that they have more substance in them than dharnas and hot air. But what did they do? Abandoned ship after 49 days, left the state governmentless for such a long time, and now taxpayers have to bear the cost of yet another expensive election. Utter wastage of money and resources that could have been productively spent elsewhere. AAP's only election plank is anti corruption, by which they presumably want to stop the pilferage of the nation's money - somebody should ask them what this resignation drama is going to cost the exchequer.
If Delhiites are smart, they would teach AAP a lesson they won't forget any time soon. That should give them 5 years to learn more about politics and governance, and hopefully they will contest next time round as a more mature entity.
