I think the bottom line is whatever these Maoists were tagged as , or whatever their approach was in order to raise awareness or revolt (mostly my means of violence, killings, threat) it is now clear that most of the Nepalese are in their favor. Was this by means of ??? Threat, love, negotiation, or promise which other parties were not able to do, the results are crystal clear.
Different Parties: They thought that government is in their pocket without knowing how much Nepali liked them.
They have never worked hard and always got lucky, but this election proved them wrong and basically they are incapable. Big figures like Sujata Koirala was dreaming of being princess and even did not bother to go to the field and campaign effectively, she just thought she is a princess and she should win and thats her right.
Future of monarchy:
I think Nepal should have monarchy as an Institution but I dont think this is going to happen. It is very risky because country might face new ethnic clashes. At the same time the positive impact it will bring on Nepali community is that the caste system will be abolished , if there is no Raja , Rani, there are no Rana- Rani, no Shah  powers still influencing in Nepal so Mr. Tharu , Mr. Chyame Mr. Bahun and Mr. Newar NOW WE ARE ALL EQUAL.
