Realistically $10m is nothing in the budget of the country. My concerns are around democracy and the disproportion from people manipulating the system. As someone else mentioned in another post, Germany didn't really solve the issue but disincentivised it by basically cutting off the overhang if the party didn't get enough votes. If the overhangs are going to come from manipulation of the system instead of genuine desire for particular representatives then we should probably do something similar. I'd be ok with some limit like max overhang of 1 per party or something that would allow some flexibility without the purposeful manipulation. That would make the vote splitting strategy a lot riskier compared to the payoff. It might incentivise more smaller parties by TBH that's what I'd like.
