That is probably the way to bet.
There is some chance for reform if the Republicans hold the house and gain seats in the Senate.
That will signal to the Congresscritters they have less to fear from the alliance of the Agencies and the Media.
FISA was a reform in the wake of the Kieth case. The government got caught snooping without a warrant, and by golly, FISA will prevent that from ever happening again.
I don't care what they put on paper. The system depends on people for honesty, and once a bureaucracy reaches a certain size, dishonesty will find and KEEP a secure foothold.
In this case, the government was snooping on the Trump campaign with NSL's, unmasking bulk data collection, and other means - long before any FISA warrant was even sought. The statute immunizes government actors who engage in illegal snooping, provided they get a warrant.
Get rid of FISA totally. It is money spent to encourage and protect aggressive snooping, not curtail it. Return to the system where the government LOSES IN COURT.
