The left has always been for big government socialist nationalized federalized programs
The old right was at least for big government on the state department, national defense, security, and intelligence side
The new right/ populist movement, however, is not just a threat to the politically elite socialist democrats as it pulls the working class away from them and forces them to import a new socialist voting base and embrace the help of CCP, but it's also a threat to the jobs/raises/bonuses of the unelected permanent government bureaucrats in the security state.
All of government and all of the left, which have already commandeered public education, academia, mainstream media, and global conglomerates and monopolies in banking and technology, are against the citizens who want smaller accountable and transparent government and lower taxes. The America first movement on the right has scared bureaucrats so much that they will use all of the tools available to them and all the tactics our CIA has often used abroad on ourselves.
