Once upon a time we were active Republican Party members at the precinct level. Then Reagan won the nomination instead of John Anderson, and Republicans became more rigid in their beliefs. It was about this time that the term RINO was coined: Republican In Name Only. And the Republicans stopped being a big tent party. This rigidity should not be mistaken for conservatism, a thoughtful consideration of change.
There have been a few bright spots like Bill Frenzel, Representative of 3rd Minnesota district, and Arne Carlson, Gov. of Minnesota after the Republican candidate imploded because of inappropriate behavior with teen-age girls. So much for the "moral" party. BTW Carlson still writes a blog: http://govarnecarlson.blogspot.com/
Since then, there have been more and more rigid stances, including eight years of obstruction of a Democratic President. Bi-partisan legislation happens too infrequently.
I would say the only thing "conservative" is to "conserve our world view" despite plentiful evidence to the contrary.
