If they erase top5 party ststem:
1) It'll be too easy to start a PTO in a small Country.
2) Too many parties will be born, with the consequent death of political module.
Strongly disagree.
Thanks for sharing your opinion!
But I disagree with your points.
1) Small countries have small population, true? Then they hardly have more than 5 parties with active people. If the Top 5 is erased, the chances of PTO are the same more or less, it depends of the electoral strategy and the ammount of votes of PTOers and ATOers.
2) Big countries have more than 5 populated and active parties, we just have to look Poland top 10, as below image from top 6 to 10
Actually top5 system is expelling from congress and CP game to 662 citizens in Poland, that although the actual top 5 system, they don't want to change to another political party, so they are actually "bored" or maybe doing extra deals with Top 5 parties. But they cannot play directly.
So the main aim of erasing Top 5 should be to allow more parties and their members to participate directly in the elections and to not depend of the Top 5 party presidents oligarchy.
As told in other post, we all see the day before of elections, lots of new accounts (maybe multies?), express citizenships for only vote, movements of players for push a party into the top 5, or to expell one from Top 5 and move it to Top 6 and disable it for having candidates (Kind of TOver tactic)
