3) The democrats were largely in power because of support from labor unions. Cats like Clinton and Biden completely fucked those voters over in the 90's. They let people's jobs get sent overseas for cheap labor to serve corporate interests. Clinton's welfare reform was also a goddamn nightmare for poor people.
A lot of Trump supporters voted for Clinton because he promised them he would veto NAFTA. A lot of "own the libs" style republicans used to be democrats until the party threw them under the bus and cost them their jobs and livelihoods.
Biden is going to lose all of the key rust belt swing states because of what he did in the senate. Y'all will be back on reddit calling those voters racist and stupid without acknowledging why Biden was a terrible candidate.
