I can’t imagine who you’re thinking of; but while I may agree with ‘brash’, I’ll never agree with ‘nutty’.
They may be right. The last guy who ran that was almost normal was Bob Dole. And he got trashed.
In contrast, when Trump mocked McCain, saying "I like people who weren’t captured, I hate to tell you.” I thought he had lost it. About 300 posts later, the consensus was that Trump had jumped the shark.
And he won.
Being a little nutty may be a good thing in politics. I'm just sayin'...
