@ican711nm,
The only way the GOP will be re-directed is to elect people who emulate by word AND track record the qualities we want in leaders. It will be persuaded by the unrelenting drum beat of reasonableness demanded by the Tea Partiers and Town Hall goers and those who talk to their neighbors, post on blogs, write letters to the editors, and consistently contact their elected leaders.
There are unreputable people who tell others what they want to hear and then do not behave accordingly of course. We elected a President like that I think. But I do believe our elected leaders are capable of reform if they understand that is the ONLY way they will retain their power.
I don't agree with your proposed solution since I don't know a single person, other than you, who thinks that is the way to proceed or who would not be offended by those who attempted such. I myself would be offended by such an attempt. I think any such attempt would trigger a fight that would split the conservative base with the lion's share going to those who do not want impeachment, even as a theory. The base can ill afford to lose those who would vote for impeachment though.
Bottom line, there are many of us who thought the GOP hurt itself impeaching President Clinton for an offense that did not rise to the level of high crimes and misdemeanors and that did not meet criteria sufficient for conviction. And President Clinton's offenses were documented crimes not sanctioned by Congress--crimes that would hold up in the courts. So far President Obama has committed no documented crimes not sanctioned by Congress or that would be upheld in the courts.
I want my party to be a) the majority and b) the party of integrity, responsibility,competence, inclusiveness, and reasonableness.
But I am open to be persuaded by anybody who can give me a convincing argument.
