"you don't give carte blanche"
Don't know what constitution you're reading, my constitution does assign elected representatives broad freedom, as it explicitly says elected representatives have no mandate obligations - it was explicitly designed to avoid to make them parties' puppets - and unable to adjust for unforeseen circumstances and needs.
Citizens can still ask for referendums if they can get enough support, and of course they are free to petition their representatives and vote them out.
The "very limited list of candidates" may mean that the selection process is not working - and that means citizens are not participating to it. So you can't really complain about the lack of participation if you don't really participate to it.
Democracy is hard - that's why most don't understand it and would like "simpler" authoritarian solutions.
