Trump's aim? I don't think he has an aim at all. It's all for the next election, he's just trying to cover up all the BS he threw during his campaign.
I don't think we will see liberals holding red flag anytime soon. Anti-communist propaganda in the US won't let that happen. let's say we go into another recession just because of Trump. Rather than acknowledging that the problem is in the system itself, the liberals will just go in blaming Trump and majority of the right will find one thing or another to blame. As long as Communism/socialism is considered a taboo, some liberals going into the left side won't make any big difference (in a long-term, it may make a difference).
Trump's failed presidency could make a way for someone like Bernie Sanders. I know he is just a plain old liberal, anti revolutionist "social democrat". but it all comes down to lesser of two evil.
