The modern democratic party is quite right of center, and that's a problem. The Democratic party is an enormous fan of corporate welfare and subsidies for industries that are aligned with their talking points. There are still a few firebrands in the party, mostly centrists like AOC and Elizabeth Warren and possibly Bernie Sanders and Ilhan Omar, but they took suck at the teat of irresistible corruption.
And this is not a both sides argument. For there to be a both sides argument, there have to be two sides in opposition, and the truth is that there aren't.
