I complain while they are IN office- and while I think my voice can make a difference. I did not vote for Bush either occasion. And I did not vote for Clinton either.
But I do not spend my energy vocalizing my issues with past presidents who are now only history. I deal with what is left to deal with and spend my energy objecting to the actions of the sitting elected officials and holding them accountable while they hold office. Once removed I move to the current situation fully realizing that the conduct of past officials effect the present.
