The GOP is a political party, not an ideological movement.
We understand that.
You will find a large number of conservatives in the GOP.
That is not true of the other party.
The GOP is at war within itself, unfortunately, with the top establishment people determined to forever “run things”.
But that’s still where you find a large, conservative, but non-establishment, seething mass of people!
IMHO, the GOP is becoming more ideologically coherent. Witness Lugar's demise.
