Welcome to Free Republic.
Ping.
Personally I think Ted Cruz should should get with Sheriff Clarke and Detroit police chief Craig along with some of the Armed Detroit ministers and possibly Detroit Firearms trainer Rick Ector for a small town hall type of event.
They can publicly discuss the need for the second amendment, the fact that there is no religious prohibition against guns and self defense even in church. They could also speak on how to spread the message.
Despite its problems, Detroit is a solidly pro 2nd amendment town and a smart republican might just make some inroads there. Even if they don’t vote republican, any advance of the 2nd Amendment is a win for us.
