Ignore them. They are just pissed off and sour grapes because Cruz is still not taking off. Vote for who you want to vote for and they can do the same.
Honestly, every thread ends up with frustrated sourpuss discussions between Cruz fans championing how great they are as opposed to all other people.
There are many more people determining candidate support that don’t post on the internet. The Cruzers can take their honey and go vent at all of them.
What you said is quite true. :-)
