As is the moderate Republican.
As it should be...
Its way past time to draw the battle lines and fight the war.
I don't see evidence of that (moderate Republicans becoming a vanishing breed). They might lose their hold over the Republican Party but I don't think they are going to go away. In fact, if many of the remaining moderates in the Democrat Party switches over to Republican their ranks could actually grow. The conservative/moderate struggle for control of the Republican Party has been going on now for over 100 years. It's not going to go away...
One sure way for the moderates to control the Party is for conservatives to leave and become Independents or reregister with a third party. We should not allow ourselves to be chased from the Republican Party.
