I'm pretty new around here, but didn't MSI sponsor a phone survey that overwhelmingly showed that Marylanders don't support additional gun control? Wouldn't something like that give some hope to a referendum passing?
You might try X Ring Supply in Newark DE. I have been able to get some Small and Large CCI primers there over the past month or so. Powder is a different story.
I'm damn glad that I have Smigiel as my representative. His office is only about a mile away. On the other hand Delaware is about 3/4 of a mile away. Perhaps time for a move.
