That’s not Cruz’s Twitter. That’s just someone using the name “Ted Cruz 2016”.
I don’t see it as a problem if he did it, anyway.
Someone is just forwarding what is on a news network, CNN, forwarding what they are reporting.
How can people claim it is “dirty tricks” when it is out there for the whole world (at least, the CNN world) to see?
It he didn’t do it, fine, if he did do it, fine.
