I agree, people should have challenged Biden and Harris in the primaries.
They should have voted non aligned and disrupted DNC events until a proper primary was held. The inaction in pushing the Democrats to bringing up a non genocide, non mass deportations, non economically cynical and classist towards the poor candidate was an issue. However that should not distract us from the institution that fought against getting any such candidate and instead pushed Biden until it was unbearable and then switched to Harris.
The inaction of the people was part of the problem. As the largest block was non voters, if these had went for an agreed upon third party instead, they could have made the presidential race even if the DNC kept blocking any progressive candidate.
At least now many people become fully aware of the true colors of the US empire and the evil it does to its citizens and people all over the world. Many people before deemed these acceptable under a Democratic president. Now is the chance to rebuild a proper political and economic system in the US. This is why it is so crucial to not let the Democrats off the hook either. There will be no healing in the US as long as the Republican and Democrat elites remain in power.
There wasn’t a proper primary for Biden. There was no primary for Harris. She just got all the delegates pledged from Biden. And they were destined to make sure that Trump or a similiar candidate would win the 2028 election if he didn’t win already in 2024. And this is a continuation of the Clinton campaign, that almost comically made sure that Trump would be the only one addressing the issues of working class Americans.
