Third party candidates are often part of the misinformation machine. Used as an attack Vector as well. The problem is Democrats cannot address everything. Oligarchs fund conservative media more than most people realize. So many outlets exist just to push a narrative. Not to make a profit. Tim Pool and several other right-wing demagogues were recently exposed for getting paid hundreds of thousands of dollars effectively a week to put out one or two low effort barely edited videos of propaganda. They made more in a couple weeks than someone like Sam Cedar for instance makes in a year. And they are just the ones we know about. Democrats simply cannot compete with or push back against all of it with the minuscule funding they do get.
