It wasn't smart when TPM made it official strategy; I was wrong thinking it wouldn't matter. I basically said that they were just formalizing an existing practice that their electorate already did.

It was well known that a lot of TMP supporters split their vote; but they still got 2-3% of the party vote. Meaning the overhang they caused was usually 1-3 seats. Not a big deal in a 120-123 seat system, and I don't recall that their overhang ever changing the result of the election.

But as soon as they made it official strategy; the right had social license to pursue the same; but with way more money and reach. I'm sure the right were already thinking about doing this type of election-engineering; but the social license afforded to them by TPM's action means that there has been almost no public backlash from this.

I was wrong, it was a big deal; overhang engineering has opened the flood gates; next election it will be much worse, unless we can get a fix in this term!
