I've had some fun getting people to explain to me why rural states should be over represented. They commit so hard to the idea of protecting the rural minority from more populous areas, then ask them why other minorities shouldn't be provided the same protection. Then they get mad.
One neat trick to ruin Thanksgiving!! Grandmothers hate it
For real, though, I try to avoid politics in the name of civility, but my dad can't resist sometimes, so this is a nice end-around. However, it doesn't really address the most likely retort, which is that (R)'s will simply claim that minorities are already overprotected.
Although, I suppose one silver lining to come out of the must recent spat of Supreme Court decisions is that those limited bits of progress that had been made to protect marginalized communities are being stripped away, so any claims that those communities are already protected are much easier to directly refute.
I'm not sure I like the idea of having three representatives from a district. I think that's a recipe to have the gerrymandered party have 3x power.
However, I am all for increasing the size of Congress. Double it! Then plan on adding some seats for every census.
Simply doubling the size of the House would reduce (but not eliminate!) The advantage smaller states have in the EC. And adding a few seats for every census could reduce the chance that a state has to give up a seat.
