This is more than a little contrarian, but many of the states where Republicans have rammed through repressive voting restrictions and pre-empted for the legislatrue the right to determine the validity of elections have done so on simple majority votes without any way for the Democratic minority to at least hold up the final vote and perhaps buy some time to organize a more effective opposition.
Instead they are left weaponless unless they can pull off a trick like in Texas where, by shear luck, the Domcratic members were able in the last hours of the last day they to walk out and deny the quorum needed to pass a truly awful bill.
Most state legislatures have nothing resembling a fillibuster, and in Georgia, Texas, Florida, Pennsylvania and Iowa, etc. Republican legislatures are able to easily pass extremely reactionary bills, strip other government bodies of their authoriy (Wisconsin and North Carolina governors, e.g.), and hold mock hearings, “audits” and other stunts to try to impose their will or at least poison the context for rational governance.
I most definitely wish to see the current form of the US Senate fillibuster destroyed. Nevertheless, I am a bit leary of doing so without any more rational ways to give the minority at least some ability to prevent someof the awfulness that takes place in many of the state legislatures controlled by the Republicans. Maybe the Democratic Senate caucus needs to come up with some well thought out alternative and take the time to sell that the the public at large so when it is put in place there will be wider support and harder for Fox News, etc. to lie about it.
Mitch McConnell et al. will destroy the current fillibuster system if and when they become the majority again. Democrats need to find a better way to deal with this issue before that happens.
