AAP’s victory is analyzed by everyone from many different aspects. The 2014 election is never accounted as a positive reason but a very bad phase. If you say 2014 was a massive failure, it was the best failure any political party would ask for but they rarely get to witness.
Your are right if you see the 2014 general election results, a rookie party lost almost all seats but 4. But you are wrong if you see how it helped the volunteers. A new party to win in such a majority takes more than decades of presence. Every election in every diff place is unique and so parties fail to expand cause they fail in new areas. But, every failure is a lesson. Other parties fail many times before they learn all the don’t-dos and finally they do it right.
For case of AAP, they fought more than 500 seats at once. The volunteers (not the party leaders) already got a heads up on loosing lessons from all parts of India. Personally, we also found out 90% about the internal workings of the “Amit Shah election winning machine”. With that overdose of experience we got from just 1 election and just 5 months, its just next to impossible for that Election Winning Machine to be able to do any major surprise tactics. And that’s why participating in nation-wide 2014 general elections is extremely critical for this victory.
I have been a foot for AAP all through mid-October-November 2013 and from March to May 2014. Have been in Delhi, Gurgaon, Srinagar and Varanasi trying to help. Hence I can validate that I myself learned a lot about campaigning and participating in elections.
