The intellectual ferment on the republican side comes from the right. Your side is furiously trying to deplatform and censor them, with the tacit and often open approval of establishment republicans. You want specific ideas? No more pointless sand wars, America first trade policy, end DACA, repeal obamacare, regulate silicon valley monopolists, build the fucking wall, no more trans, homos et al in the military, no welfare benefits for immigrants, end sanctuary cities and do whatever it takes to stop the mob violence that is ruining our country. What are your big ideas? Abolish ICE, open borders, free everything for everyone, censorship, delegitimize everything from the Constitution to the Supreme Court, and of course, blame whites for everything.
