since you have to be alone in the voting booth and your vote is anonymous it can't be bought.
You can say that you voted for X, but vote for Y and noone will ever be able to tell.

How does it work in Italie? I can picture easely how someone in the paper room can put pressure on you to only take one paper.
Also they always give you all ballots, I don't recall ever being asked which ones I wanted. Plus at all points you are always in front of multiple people, I believe each candidate / party in an election gets to appoint someone to keep an eye on the proceedings
(Also the original claim about 20/30% seems like abject fantasy to me, unless we take the entirely different meaning of "20-30% vote for a candidate that organized crime is happy with, which is entirely unrelated to electoral interference)
