I'm sure there will be no complaints whatsoever or we may say complaints are ignored if the fruits of his promises came to real and their country improved because of him in the first 3 years of whoever president has been elected. but guess what? at that time, their true colors will be revealed and most probably they are just the same as the last one. Let's give this guy time to do his thing because after he got elected, he has all the rights to make his country bright and shut out all the causes of corruption, and become their first ever just leader elected by their people.
If you made a manifesto for a presidential candidate or any political portfolio and the eventually emerge into office, that does not guarantee they will remember you to favour you or not except you're just being lucky for them to still have you in mind, this is the same thing that goes with others, they will believe the new government is not giving attention to their demands whereas there are alot of people in demand, but if you want to please everyone, you may ended up displeasing everyone, it's better to do your best with being bias and leave the rest.
