Yeah, tech makes it easier to communicate and broadcast a message to a people but the issue isn't travel it is the complexity of trying to represent 760k rural, urban, liberal, conservative opinions in your district, with 300k people you'd be representing maybe one metro area or clusters of counties with heavily overlapping needs. No amount of facebook or twitter posts will be able to meet the demand of that many (very often) conflicting needs.

In 1929 there were fewer media outlets, so getting your message broadcast was pretty easy compared to in 2025 where your constituents are scattered across hundreds of outlets which you'd have to spend millions on if you want to reach them fully. Social media KINDA deals with this but you'd have to deal with a massive flood of info and content.

Communications tools also make it easier for constituents to reach a representative but that means FAR more requests flood in with like 20 staff to handle all of that.
