—RINO—
That is a tough term to define. There’s no GOP manifesto that says it has to be conservative. Indeed, before Ronald Reagan, most of the GOP’s big shots were mushy moderates; Richard Nixon, Nelson Rockefeller, Howard Baker, Gerald Ford Bob Michel, Bob Dole all come to mind. The conservative movement MUST not hitch itself to a particular party. And, yes, I think the GOP may be moribund; in fact, it might be in the same shape the dinosaurs were at the end of the Cretaceous, right after the meteor hit.
They were living in a very liberal era. Some of them, like Rockefeller, were quite liberal. The others were doing what they could to counter the Democrats.
More recently the GOP had a much higher percentage of "conservatives" in Washington and ignored most of what conservatives had been talking about for years.
Get rid of the RINOs or the whole GOP and in a few years things will be pretty much as they were. Voters more or less get what they want.
