Isn’t it the ultimate irony? D-s are saying that in order to protect various minorities they need to abolish a legislative practice that is directly protecting .. minority opinions.
There is a legitimate reason against filibuster – that it light lead to inability to address issues of importance to the country and make the country lose in international competition. This happened in Polish Seim where each member had a veto and Poland ended up falling behind and being swallwed by empires around it. I don’t think US is in this position (yet). I don’t see 40 pro-China or pro-Russia senators stopping us from addressing external threats. If we don’t spend another $2T dollars immediately, the republic might survive.
