I think you'd benefit greatly from reading "Brainwashing" followed by Masses, Elites, and Rebels: The Theory of "Brainwashing." My strategy entirely changed after reading these, people will not side with you truly if they already license themselves to believe something else. This coincides with the real experience of Communists and other Leftists historically, Liu Shaoqi's How to be a Good Communist talks about maintaining this honesty in dealing with the rest of the Working Class who may not be radicalized yet. This keeps us in touch with their needs and desires, preventing commandism or tailism.
American conservatives are not going to align with any kind of Socialism except for PatSoc movements like the American Communist Party (not to be confused with the CPUSA), also known as "MAGA Communism." Essentially Imperialism combined with Communist aesthetics. This needs to be combatted direclty. Cubans leaving Socialism because their slaves were taken away by Castro are not going to have the same class characteristics, same with small business owners in the US.
Over time, as the conditions in the US Empire decay, more conservatives will be proletarianized and open to Communism and Socialism. It is a danger to let these narratives be driven by Nationalists in the Imperial Core.
