Interesting discussion. The Democrats, almost to a man/woman, want to define RINO in the most perjorative manner possible while at the same time using all sorts of ad hominem against Republicans in general.
The conervatives, however, including Bripat, seem to be pretty well unified on what the definition of RINO is which is a 'liberal' Republican; i.e. one that goes for big government solutions to all problems.
Republicans who aren't RINO can be as socially liberal as they wish, even pure libertarian, but they won't look to the federal government to promote a socially liberal agenda. President Bush's 'No Child Left Behind' program, for instance, was pure RINO. As was his Senior Prescription initiative, his energy policy, his environmental outlook, and his views of immigration.
Republicans who describe themselves as conservative, such as a John McCain, will still be a RINO when they join with Democrats to push a big government solution for a social issue.
It isn't that we object to anybody working with anybody to pass good legislation. But when Republicans go with the Democratic agenda in passing what conservatives consider bad legislation, then those Republicans will be branded RINOs. The hypocrisy shows up though when those who point fingers at Republicans for resisting what they consider to be a bad piece of legislation coming from the other side, never seem to mind when Democrats resist Republican proposals.
There are dozens of really good bills the House has passed recently that Harry Reid is not allowing out of committee in the Senate to even be debated, much less voted on. Where is the objection to that from you guys on the left? Are only Republicans supposed to work with the other side but that doesn't have to be reciprocated in your view?
Unfortunately the Republican party has been more big government oriented than not for some time now, though they often do show some more restraint than do the Democrats.
If the GOP doesn't turn it around by 2012, we conservatives may really have to start looking seriously at a third party in order to have any representation at all in Washington.
