“Citizens complain. Then keep sending their rep and senator back...
over and over again. Insane.”
Yes, because it’s always “our guy is a great asset,” but the guy in the next district is a “disgrace.” It’s like Texans nominating Ted sCruze, because “he’s their guy,” even though he’s not native-born and quite likely isn’t even eligible to be president.
It's the same reason that we never get spending cuts. The federal dollars allocated to the other state or district is "pork." The federal dollars allocated to your district is always a critical project well-worthy of federal spending.
