I don't know about the percentages, but I think the majority of people who would see a tax cut are those who bought property in the past 10 years at inflated prices. The people hurt the most will be those who've been living in the same home they purchased 40 years ago, and are clinging to their tax assessment that's orders of magnitudes behind what the current assessed value would be.

There are ways to fix that too with gradual phase-ins, not allowing people to pass their tax assessment on to their heirs, etc. But anyone who stands to inherit property will vote against such a move, and most people who will be passing along that property will vote the same way.
