The biggest debate within the conservative movement is over immigration. Beltway conservatives think we need to return to certain "principles" and just convince everyone that we have the right idea. Nationalists are under no such illusions. Demographic change has political consequences. And one of those consequences is redistrciting. 

Conservative Review reports:

The Center for Immigration Studies published new estimates of the 2020 census that show states won by President Trump wind up losing 24 seats in the House, corresponding with a loss of 24 electoral votes, thanks to mass migration and our policy of counting immigrants for reapportionment. In total, 26 seats are transferred as a result of factoring in total immigration, which includes those who became naturalized. If you just look at current immigrants who are not naturalized, they cause a transfer of 10 seats, thanks to the policy of counting them along with citizens in state reapportionment. To put that in perspective, Democrats control the house with a majority of only 21 seats, yet that majority is built on the policy of counting immigrants in the political process that should be controlled exclusively by citizens.

Furthermore, even those "red states that will gain seats won't remain red for long.

Overall, 19 of the total 26 seats transferred in reapportionment due to immigration will be awarded to “solid” Democrat states: California, New York, New Jersey, Massachusetts, and Illinois. Texas is the only red state that stands to gain seats from immigration, but that is also partially why its shade of red is dulling rapidly.

It can never be repeated too often that all of this was unnecessary. The conservative movement was warned. Peter Brimelow told them this would happen. They didn't listen, and so now the GOP faces the real possibiity of becoming a shrinking, regional party. 

There are many possible solutions to this problem or new political coalitions that could form. Yet my question is much simpler. Will anyone in Conservatism Inc. be held accountable for this? Will any of the heads of those "nonprofits" raising so much donor money ever admit that Brimelow and those like him were right and they were wrong?

Not likely. Like those who cheerled the Iraq War, no one has suffered any real consequences. So why should we believe any of them about anything ever again?
