Do you think the best way to think about politics is to choose to be how left or right issue by issue you are?

Could one think about and write downl the issues one cares about to try and hint at what one cares about politically then to rank them one by one as truthfully and objectivly to oneself as one can for amount left or right on each issue as well as one's overall instincual gut feeling of leftness or rightness to try and hint at a self essment of what ones personal position on the spectrum of left to right truely might be and see if it makes sense? I mean not totally depending on this but as just a small part of how a person picks a political position and perhaps what changes they want to see there to there parties positions on certain issues? And when one is discovering what ones position is it would be nice if they tryed to include the seperation of church and state and what that truely and objectivly means to them in there considerations of there positions issue by issue? I feel like this would help both the party's to at least deal with curruption because neither party wants that.
