In addition to the electoral college and giving each state two senate seats (regardless of that states population), another related thing I’m in huge favor of is giving states more power to shape their own rules and policy vs. centralizing power in DC.
I love the freedom you have in this country to move to another state if you don’t like the politics, taxes, etc… in one state. I moved from Kalifornistan to WA State partially to escape the oppressive state income in CA (WA has NO state income tax). I LOVE that I have the freedom to do that. This allows people to “vote with their feet”. It would suck bad if Wash D.C. controlled individual states more then they do.
I don’t think you have this freedom in a lot of other countries, to move to other areas to lower you tax burden or get a political environment more to your liking. Socialists and a lot of Dem’s would love to take this freedom away and centralize power in DC.
