I wonder if democrats realize that the Supreme Court could simply strike down any such expansion as Unconstitutional. (and before anybody says there is nothing in the constitution that says the democrats can’t, remember that has stopped the Supreme Court from “finding” rights to abortion and gay marriage, so why not?)
They do, but they also realize that the illegal, unwarranted (in a legal sense) collection of personal information and monitoring of personal communications (not just phone conversations, but also emails) that was used against candidate/President Trump has been used against others, including Supreme Court justices, for years.
