I was one 'til 2006. One of the reasons I resigned is because I would be obligated under our bylaws to support the R nominee and I was concerned it would be McCain.
If your bylaws require you to support the R nominees, then I would respectfully suggest the correct course of action is to submit your resignation. But your bylaws may be different than ours.
Every time a Conservative resigns and a not-so-conservative takes their place, the GOP goes a little farther to the left.
We need MORE conservatives at ALL levels if we hope to TAKE BACK THE GOP.
Otherwise, were just giving it away.
