Reasons for the shamful defeat of NC / UML:
1. You have overestimated yourself = You have underestimated your opponents. No research nothing. Just imagining. Som sarma ko bau ko katha padhnu parne thiyo. 10% can be attributed to this reason in the case of NC's defeat
2. YCL / PLA did not let NC / UML cadre trickle down to people. 50% can be attributed to this reason in the case of NC's defeat.
3. Too much dependent on corrupt and unreliable news media. NepaliTimes is the only media that I trust. I trust Kantipur only 80% reliable. 5% can be attributed to this reason in the case of NC's defeat
4. The NC / UML were engaged in group masterbation for last 7 years. 10% can be attributed to this reason in the case of NC's defeat.
5. They did not have guts to reach to people with any reliable agenda because of their corrupt background. 50% that overlaps with Most of the other reasons. P(5th reason) * P(all others) =  shamful defeat. Intersection.
6. The same old faced in Party's CWC in a country where majority of people are below 30 years old. 10% can be attributed to this reason in the case of NC's defeat.
7. Did not use student wing in more intelligent way. 25% can be attributed to this reason in the case of NC's defeat. It overlaps with others, needs to use Bayesian Statistics.
8. Failure of Koirala Family to realize to transfer the NC to people's choice. Sujata Tantra: Sujata became a minister without a portfolio. Sushil (htough he is not relative of GPK) being a chamcha of GPK, failed to work as a leader, but was not able to grasp what was going on in the country, and people's mind. Not able to get rid of Khume, Govinda, .... so many corrupt faces out of CWC and party as well. 50% of the area for reasons is also jointly covered by this reason.
9. Maoist agent in Home Ministry: kickbag Sitaula. Failure to provide security by controlling YCL's monopoly. .... it covers 70% area for the reasons to be a shamful defeat.
10. Lack of professionalism. NC and UML never promoted professionalism. The NC and UML leaders never had any educated people in their advisory board. They simply don't understand statistics and modern technology. They could have used Internet. 10% can be attributed to this reason in the case of NC's defeat.
