This is a very very late reply to your comment. But this party isn't really a Marxist party, they used to be called JVP but they renamed themselves as "NPP" and rebranded themselves as a center left party hired a banger marketing team. And their leader has been very vocal for the longest time about the corruption in the government. But they never won cuz their party had a big black mark cuz of their past (JVP uprising) and no one really wanted to risk it voting for a party that has never ruled before. The two major parties that always used to grab the highest votes didn't win this time cuz people were tired of their leaders, every term the ball gets passed from one side to the other and that's it at the end of the day they're all same they're all buddies, it's just all show in front of the cameras but thet done and wine behind closed doors. Both parties have been taking turns robbing the country. So naturally this time because of all the talk on social media people wanted a third alternative and this so called Marxist party was their answer. During their campaigns all they said was we know you're fed up with the the rest, give us a chance we'll do things differently and we'll do it right that's all. In a way this party winning is a people's experiment. Cuz everyone collectively was like "we're fed up of these two other parties, this third guy has been very vocal and open about all the corruption mismanagement so let's see what he can do different to the other two, if he too starts stealing we chased one guy out we can chase him out too" and that's basically how they achieved a landslide victory. And tbh so far the ship has been smooth sailing. But time will tell.
