The Republican trend has been to worry less about their constituents as Republican voters care less and less about the actions or policy of their representatives and more about what conservative media is focused on. This makes money a far more effective means of deciding who holds seats. Money has always had an outsized effect on who wins their seat come next election, but where some candidates could succeed despite their oponents out-spending them, the republican party has become almost entirely "pay to win."
Americans need to expect their living circumstances to continue to decrease as representatives increasingly service wealth holders instead of constituents.
