That first link seems less reliable than Daily Kos, so no comment.
As for the second link... Yeah. Trumpism is winning over Republicans. The problem is, he's driving Nice Polite Republicans out of the party. That's how you lost Alabama in a special election with mid-term like turnout. Celebrate this all you want, it's not a positive for you.
Imho each passing day increases the likelihood of a GOP split and a big time conservative independent in 2020.
Agreed with this, or a major realignment (or both)
You folks cannot read and do not understand. Instead of the GOP being Trumpized, he is being GOPizd. He is appointing conservative judges up and down the line, he is adopting the strong GOP foreign policy position (no Russian lackey is he), he is stronger in his support of Israel than even other Republican President, he is building up the military, you will see him allow the dreamer stay, he is cutting regulations. He is following traditional GOP policies.
There will be no big time conservative insurgent in 2020. I supported Kaisch after Rubio dropped out in desperation. But he was always a fool for running in 2016, as he had no support at all in the south. To win the GOP nomination a candidate needs significant support in the south. He still has none in the south or anywhere else.
So who will this big time conservative be? McCain will be dead. Romney and Jeb have no support. Flake, who cannot achieve renomination? It is more likely that if Trump thought he did not have a chance to be re-gelected, he would declare he had achieved his goals and choose not to run again.
Realignment. Right now I think you are putting the cart before the horse. 1964 and 1974 did not destroy the party. If the Democrats continue there anti law enforcement positions, they are going to get a backlash from the WWC. Remember most local police are WWC. There policies of continuous income redistribution will run into problems with the white middle class.
