I could make a pretty compelling case - to me at least - that the exact opposite is true in this day and age. At the core of the Trump brand of republican politics right now is a very real and very measurable feeling and position of those very same 378 that no one cares about them anymore, their jobs are gone, they feel like they are blamed for problems that they were most likely never a part of, and a huge part about what gave them an identity has changed or disappeared with nothing to take its place leading to a vacuum of fear that has been seized upon by Donald Trump and the people that support him.
In this day and age we need to reach out to those 378 people just as much as the 378,000, not less so. And debating from thousands of miles away that we should ignore them will drive them to the arms of people that gave us this presidency. No thanks.
How about instead of fundamentally altering the constitutional framework of the nation for immediate political effect, we actually do the hard work of solving the real problems that we've made, ignored and fueled by ignoring them or putting band-aides on them? We do prioritize people. All people. Isn't that the point? You won't win any hearts and minds of the very people who you need to win over to truly cure the sickness in this country by telling them they don't matter because they don't live anywhere near a 10 story building.
