"The second he's not useful, the GOP dumps him," tweeted Alex Castellanos, a Republican strategist and CNN contributor, who likened Cruz to an escort hired for a class reunion when you can't get a date.
 
Castellanos has missed the point.  Circulating at a class reunion with a gorgeous woman can be an ego boost but it is the personal "reunion" with the lady before/after the visit with fellow alums that makes the event memorable.
