I'm not sure how I feel about this.
On one hand, yes, some elections do have the minimum required candidates (which is frankly concerning), and it is
generally better to reduce the size of non-necessary government; however, the House is currently a fairly quiet body already with nine members, and seven members would (likely) make it even quieter, the House would statistically become less representative relative to the popular vote (given the multi-party system we have now), smaller parties that have been able to get in to a nine-seat house would likely fail to get into a seven-seat house due to the large (now) more concentrated popular vote from the larger parties (side note: with such a small House, it should likely become nonpartisan), and with such a small House, decision-making power would be vested in less individuals, potentially setting the stage for more controversial bills to be passed/failed quicker (I should note the Senate
does only has six members; however, the House with its nine members serves as a check on the Senate and vice versa).
I don't think just because another house proposed something that concerns the way our House functions should rush us in getting this passed, but instead it should make us consider fully and carefully the potential effects of this getting passed.
