Shocked?
Not at all.
Surprised?
Yes; Surprised that it's not worse!
Heidi Cruz is not running for president, so who cares? Remember when Trump said he could shoot someone on 5th Ave. and his people would still vote for him? The same is true of Cruz’s voters. It will make no difference what his wife has done.
There is too much bad blood between the factions in the GOP. As a result, The Clintons will be the winners, and Hillary is going to be the next president.
