It’s not left vs. right in US politics. Leftism is not represented in US politics.

It’s rights vs. theft.

The Republican Party has become the party of thieves, traitors, scammers, child-rapists, and terrorists. They represent wage-thieves, gay-bashers, pedophile pastors, Proud Boys, MLMs, crypto-bros, coal-burners, book-burners, police gangs, and the Russian Mafia-state. They are the local franchise of the international fascist movement, the conspiracy of far-right parties largely directed from Moscow.

The Democratic Party has moved into the role of a center-right party: keeping capitalism working by keeping business honest; supporting the nation’s allies; expanding worker protections within the capitalist system; building infrastructure and state capacity; etc.
