Well, the tagline of the book is "Inheritance. Fraud. Deceit.", so "Lucky" might not be the right word.
It's interesting to look at opinion polls pre/post election. All through Obama's last term the conservative rallying cry was the economy was bad and migrant caravans were coming. As soon as Trump was elected, there was a 40 point swing on conservative's opinion on the economy. It's not just the economy. It's every position. When Bill Clinton has an affair, then family values are incredibly important. When Trump brags about grabbing women by the pussy without consent, it's just locker room talk.
I think the political instinct trump brought, and that you're alluding to, was his ability to never admit being wrong about anything. Yes politicians have always done this to some extent but he's taken it to a whole new level.
It's the method of saying what you want people to believe and think over and over with complete confidence until they actually do, even if it has no basis in reality or is stupid and wrong.
It's incompetence as a political platform.
And other politicians have noticed how well it works, so now they do it to (see: hegseth).
Thanks for that ref! I've always maintained T is extremely dumb, He goes towards far left on the Dumb scale on the levels which you'd have never seen before. But, at the same time, he has all the luck which no one else has. Glad, I'm not the only one to see him that way.
