Politicians don’t serve chicken. They make and then try to fulfill promises about how they’ll manage and regulate the processes by which people can obtain chicken.
With Biden, you can at least have a coherent public discussion about why the glass is in the chicken, how to get the glass out of the chicken, to what extent the chicken distributors are influencing the politicians, etc. With Trump, we will continue to argue in circles about whether the glass is even there, with Trump’s antics at the center of attention. (What glass? He doesn’t see any glass. And if there is any glass, and he’s not saying there is, then [whoever Trump’s picked as enemy of the week] put it there, and Trump is doing better than anyone at getting rid of the glass, believe him. But what glass?)
With Biden, you also at least have someone making the motions of giving progressives more of a seat at the table, and of giving progressive issues more consideration. Regardless of how genuine or substantive you feel the effort is, it at least moves the Overton window in the direction of progress on social and economic issues, and away from the growing authoritarian tendencies of the Trump-Republican administration.
Take, for example, the unity task force that Biden and his team put together shortly after gaining the nomination. Sanders: ”‘Though the end result is not what I or my supporters would have written alone, the task forces have created a good policy blueprint that will move this country in a much-needed progressive direction and substantially improve the lives of working families throughout our country,’ [Sanders] said in a statement, emphasizing that Democrats’ left and centrist wings need to come together in order to defeat Trump.”
