In 2021 the dems created an expanded child tax credit. Its beneficial effect on child poverty was sweeping and shocking quick. Giving people money to help with their bills worked like gangbusters. Who knew? Manchin complained that people would use the money to buy drugs. Then the dems simply let it expire. If I remember correctly and I might not - I think it was in effect for ~9 months or something. After it ended - the democrats moved on and they have pretended it never even existed.

As time went on there were some unironic lib op-eds blaming the GOP for ending the program.
