The “DC insiders” are using Cruz as a useful idiot to bugger up the primaries’ results. When that mess is over they’ll kick him to the curb and bring in Jeb or Romney.
Eventually, Ted will figure out that he is just a pawn. Just as John “One Trick” Kasich figured it out after Ohio.
Of course, they will. And he knows it.
Likewise, though, he'll kick them to the curb an uite with Trump to deny Jeb or Romney (or Ryan) a 2nd ballot victory.
Bringing about Cruz' objective -- a 3rd ballot head-to-head showdown between he and Trump.
(For the record, you've already stated you won't support Cruz if he wins the face-off.)
