Okay, that's fine.
Trump did an important job of waking up the Republican party (see comment #34). The only ones who are concerned about Trump's current support are Dems. Meanwhile, Trump has a ton of support and, because of that, he has a lot of influence. Lots of voters like the strength and straightforward (non-swamp) approach Trump brought, and still brings, to traditional conservative beliefs. Lots of us still love that about Trump. So, I expect he'll have a lot of support for quite a while. But, conservatives don't care about or worry about if his support is holding, lessening, or growing. Who cares? It appears, only Dems (and Trump, lol).
Personally, I'm quite comfortable with the current Trump role. I like it. I like to learn of his endorsements and I notice those recently Trump endorsed candidates jump by large amounts in the betting markets, as Trump announces additional endorsements. Thus, I'm clearly not alone in noticing and paying attention to whom Trump endorses. By the time the 2022 election happens, I expect that will be MANY endorsements - and great, IMO!
What the Dems miss is that Republicans aren't hung up on Trump running or not in 24. I think his current role is great.
The other thing the Dems miss, IMO, is viewing Trump as an extremist. Trump, the personality, creates tremendous notice, love and upset. But, Trump the policy, is just good old fashioned, pro-America, conservative ideas. The "extremist" wing resides in the AOC branch of the Dem party.
