Sorry Im a little baby ML from the US, who has a LOT of geopolitics to catch up on.
EDIT: The reason I’m asking this is because, at least what I am getting is, that the general consensus is Greece will most likely go socialist next, but also that KKE has some issues.
You should check out SolidNet, which hosts statements and website and even contact addresses for many communist parties. Also, the website of the KKE has an English language version which you can read to check out the party statements.
This is the best answer I can give, considering I also have no idea about the internal politics of Greece
