Someone brought up a very good point; Why did Cruz drop out suddenly (after vowing to stay in to the end) AND SHUT UP after the possibility that his father was caught passing out leaflets with Oswald?
Very suspicious for the narcissist to just disappear and clam up.

We have to remember that.

Things happened quickly but he vowed to fight on, I swear I remember that.

And he then very suddenly and very unexpectedly dropped out.

We cannot let this go down the memory hole.

One possible reason for a sudden Cruz drop out is that his donors had already put him on notice that, if he lost big in Indiana, the money would stop.

He lost big and had no choice but to drop out ASAP.

As to his being quiet since dropping out, he is most likely depressed about losing and just has nothing to say.
