"We" voted our leaders in, because we want to them to deal with the "big problems", once done, it is too late to disagree with their decisions, therefore we must stand by then in their hour of need. We can remove them later if we feel that they failed us. That is the whole point of democracy.
They see "the bigger picture" because they are privvy to one hell of a lot of info that we are not, so lets let our elected sort this out on our behalf, because in theory that is why we elected them in the first place!
I support them however please note I would rather eat my own spleen that vote labour!
