This is very much up for debate. Elected officials actually have free postage and can send letters if they need to. Not only that, they likely enjoy direct access to their local news networks and can broadcast messages through that avenue. Most have email lists, and can send interested constituents updates through that platform. Most also have websites on official .gov accounts where they could host press releases as well.
Not everyone has a Twitter account, and I think you need to seriously reframe your perspective if you think it is the cure-all for delivering news to constituents.
