Known, sure. Presidential candidate level known? Not at all.
Crazy? Yeah that's it. So you think Haley and DeSantis are loud and/or crazy? Maybe Trump is but I don't think that speaks to the rest of the lineup. Like at all. Vivek tries to be loud but his shtick is wearing thin on many. And I was a big fan prior to the debates and the Israel/Hamas war.
Let's see, on the Left.....Bernie Sanders. Gavin Newsome, Gretchen Whitmer. I think y'all have a fair amount more of crazy on your side vying for the limelight if you ask me.
