Congress has received plenty of negative feedback from their voters. The intensity and frequency of Republican voters confronting their representatives over many administration policies (e.g., Medicaid cuts, ACA subsidy cuts, tariffs, Epstein, influence of unelected officials) when those representatives hold in-person town halls has led to representatives greatly reducing in-person town halls, replacing them with tele-town halls so they can cut off people.
