I am in agreement with you on the lack of NG going to more states.
I can however say anecdotally that I know our son-in-law expressed some concern about backlash in AL. He is retired army, works for a defense contractor and has had some dissatisfaction with some BLM activity in Huntsville.
It didn't make national news but one of our granddaughters was caught up in their demonstration while driving home from work one day. Granny felt an immediate need to drive to Alabama and become armed security but Grampa put his foot down and hid the car key. (Ok maybe he just repeated his worn out speech about me being a helicopter mom, or in this case helicopter Granny. He seems to think the kids are adults and can handle themselves, which is true.) Anyway, this son-in-law is glad that the NG will be in some of the AL locations with high populations of BLM supporters.
I guess AL is like TX, in that they are a majorly conservative red state with a few pockets of idiot liberals in cities.
As for the states like Oregon where we all really want that NG protection, are elections covered by the same rules as riots where the gov has to invite the NG? The Constitution leaves election laws to each individual state so I don't think Federal law can supercede a governor who refuses NG protection.
Check the last sentence of Q 45 from 11/1/17:
Organizations and/or people that wish to do us harm during this time will be met with swift fury – certain laws have been pre-lifted to provide our great military the necessary authority to handle and conduct these operations (at home and abroad)."This time" is the days after "11.3". "11.3" now appears to refer to 11/3/20 -- Election Day.
FTA: 'Crucially, after the Civil War, Congress added a provision allowing the president to invoke the Act without a state’s permission if the state is failing to protect the Constitutional rights of its citizens.'
If invoked, no permission from Governor required, AND can federalize that state's NG to handle issue.
