Theoretically possible. Is it practically possible? Because if these groups are meeting with my members of Congress and I practically can’t, then that’s not the same.
That said, for single-person "I want to tell you about thing X", a staffer probably works just fine. That's why they're there.
For a local politician, who likely has much more impact on your day to day, this is all far easier. They're generally less busy, less travel, and more approachable. And, they're the ones setting real estate taxes, school policy, and other things that make places truly livable (or not).
