Voters commonly condemn politicians for being insincere, but politicians often must disguise their true feelings when they make public statements. If they expressed their honest views-about, say, their party's policies-then achieving politically necessary compromises would be much more difficult. Clearly, the very insincerity that people decry shows that our government is functioning well.
Achieving political compromises is not all that is necessary for the proper functioning of a government most seriously undermines this reasoning.
