I'm expecting the Republicans to continue some of the concepts that Trump popularized: expanding american manufacturing, opposing free trade, and an adversarial approach to China.
Trump's nationalistic approach was decidedly successful, and was/is popular enough to offset the fact that half his supports don't like him (from a personality perspective). In many key states I see Republicans outperforming Trump down ballot (NC, MI, AZ, ME, and other senate races). The Republican brand is more popular than Trump himself. The next steps for the Pubs is pretty clear; keep the more popular Trump ideas but dump the hate and toxic personality.
The interesting thing in looking at Joe's messaging this time around, we've picked up on some of Trump's non-toxic ideas. I saw plenty of campaign ads about manufacturing covid protective equipment in america. Joe also has been talking about coordinating a global front against China's expansionism and abuses, which is a pretty much a 180 from both his and our party's prior stance of wanting increased relations with China.
I'm hoping that there can be some common ground found, and that the Republicans will want to keep the few ideas that Trump introduced that resonated so well that we're even borrowing them. This gives us a starting point for rebuilding bipartisanism, which in time will help us mellow out out national politics.
