We’re you around for 2016? Club for Growth did all they could to stop Trump
And supported Trump in 2020 and support some of the same canidates as Trump today.
There many pro Trump supporters today. Some are Conservatives that did not think Trump was as Conservative as he was a “populist”. Trumps policies generally after elected and particularly his judicial picks convinced many GOPers who wavered on Trump in 2016 to support him in 2020.
And there are some fine Conservatives running who are not given an official Trump endorsement and some questionable folks (Like Dr Oz) that have been given a Trump endorsement.
I look at the Candidate more than who is endorsing them.
