They wont vote for or against Flock. Thats not how it works. Flock will be in an NDAA or Omnibus bill. It will be "We have to pay our veterans", or "This bill will keep the government funded". Then every one of these assholes who want cover will say "We dont like the Flock stuff in the bill, but we have to pass it for reasons". No one gets blamed, and Americans hate "other congressmen, not my guy".
Flock is something each and every one of them will believe is good for the country because "terrorists" or "anti-semites". In reality, it's just so when they decide they dont like what you say, they will find a reason to come get you. America is dead, long live America.
