They need to make themselves feel better by believing could not have made a better choice.
It doesn’t matter that federal Democrats enabled the largest wealth transfer in the last 3 decades with ACA, by the smallest of margins. Or that a Democrat president increased the overtime exempt wage from $30k per year to $50k per year. Or that Biden tried to get paid parental leave and paid sick leave, but was thwarted at every turn by a Republican Congress.
The important thing is for the voter to not take accountability for their actions, so “both sides”.
I write this not as a “Democrat” (I despise them on the state and local level), just as someone who has seen Republicans literally only pass tax cuts and reduce women’s access to healthcare in the last 3 decades. Oh, and try to overturn an election and then pardon traitors.
And steal a SCOTUS nomination opportunity.
