You’re generalizing a bit when you talk about electability.
Trump has shown an important feature in that regard. He is getting the politically unwashed to care again.
By raising the personal caring rate in America, he is doing more good than Cruz alone could.
This may yet end up being a tag team, even as a Trump led ticket.
But I don't think I am guilty of generalizing, I am actually saying it is too early to generalize. It is the Trump supporters who want to leap to the conclusion that he has the stuff to get elected in the general election.
