Well, I am a Trump Supporter. I signed up to volunteer, so I am a full supporter. However, I have to say the Cruz campaign does have an excellent ground game. They have lots and lots of volunteers. I attended the CA GOP convention this weekend and there were lots of people in red shirts and wearing Cruz stuff. Nobody compares to their ground game. The problem for them is that most of the VOTERS like Trump better. I believe in a great ground game. But in this case, it is not going to help Cruz win.
The ones with red shirts that say Cruz can probably be reversed to the red shirt side that says Bernie.
