Ted Cruz has a lot of conservative support and could launch a third party bid with some success. He should seriously consider it.
Who accused Trump of being Perot v2.0 for talk of third party? I’m not saying you personally, but that third party talk has run its course.
Unless you’re just afraid to admit you’d rather see Hillary or Bernie as POTUS.
A third party bid by any Republican candidate will guarantee that Hillary becomes next President.
I don't know how old you are but you may want to research Ross Perot's bids for Presidency. Ross, a Republican, ran as a 3rd party candidate and we got Bill Clinton.
