Regional constituencies allow politicians to select the voters they want in many respects. The UK might look very different if they had a party list or some other form of PR.
Sure, i have no doubt the system is broken in lots of ways.
I'm just saying that one way in which it's not particularly broken is whether they listen.
They do nothing but listen, have dedicated staffers and help that do nothing but analyze constituent opinion/views/etc.
You will rarely find them doing anything that is going to go against that. The exception is the small number of places where they are forced to deal with multiple constituencies for real.
