For clarity's sake, this is about how their presidential election viability is portrayed by would be "experts" and with absolutely zero relation to them winning local elections (literally the most obvious observation one can make).
Basically, go find any articles that center on Ted Cruz being disliked by the party as a fatal flaw to his candidacy. It was definitely well known before he even announced, but it was never a headline story set up to define his candidacy like what's on display in the tweet I quoted. If you can find some of those receipts, I'm open to changing my mind. There's a difference between Cruz being well known for not being liked and still having coverage his candidacy focused on issues like his Immigration stances versus Elizabeth Warren having three robust bills on the table right now but having her candidacy boiled down to "can people like her?"
