I don't claim to be a legal expert, but I can't see how a case could be on MORE solid ground constitutionally.
The case filed by Texas is very simple..the only body who can make law is a legislature. Not a court. Not a SOS. Not a governor. NO-ONE can MAKE law other than a legislature. And MI, GA, PA and WI all tried to by changing the voting law via the courts and/or exec branch (eg: SOS).
That's illegal, and as much as a "tee up" violation of not only the US Constitution but basic common law as it gets. There's also the issue of "Equal Protection" which says MI, WI, PA, GA can't treat their citizens in a way that advantages them in such a critical issue as voting over another state (eg: by not holding signature verification to equal standards..that'd mean a PA "absentee" voter has different rights than a say, OH voter)..no go.
If SCOTUS doesn't take it, the only reason will be political - it's certainly as "rock solid" a LEGAL case as you can get.
I agree with you- but also think SCOTUS may see it in a different light.
I don’t know how judges think or how they weigh things. I will look forward to anything Justice Thomas has to say.
