Funny, we didn't hear much about the "tyranny of the majority" during the Bush Administration. Back then, it was, "we won, you lost."
In fact, the majority's power has been structurally reduced in nearly every branch of gov't for the express purpose of providing levels of infrastructure and public services for electoral minorities that could never be justified if the "free market" actually ran its natural course there.
So, in fact, the bicameral system, which exists at the federal level and which model Bob suggests at the state level, is a disguise for the "socialist" subsidies for rural areas that have been in place since at least FDR's time, when rural electrification brought the power out there so all you guys who think you're "independent" from the cities could blog about that now.
How 'bout that for irony? Ingrates using the resources the "socialists" provided them to complain about "socialism."
