NJ is the same way where Trump won’t win NO MATTER what because it will NEVER be allowed to happen. That being said,I have passed town and county Trump rallies,flotillas,car rallies and the signs are endless. NJ is deep deep forever blue because they harvested and gerrymandered the last Republicans out.
Reliable red states like TX and GA need to watch out for urban areas like Austin and Atlanta or they could turn blue as well.
The Republicans need to start making plays in these urban areas. If Trump did not make plays to the Hispanics and Blacks, he would not be on his way to re-election like he is today.
That's what happened to California. A lot of gerrymandering by Willie Brown, Jerry Brown, etc. to recarve district lines to favor Democrats. The Republicans were pushed out.
