If the GOP can truly ditch neo-cons and their corporate bedfellows, they could retain people who stopped voting Left and started voting Right. I think the main issue for a lot of people who recently started voting GOP is that the Democrats and their acceptance of Woke culture is more frightening than the current state of the GOP. I'm included in that camp.
We're seeing it now in that "Conservative" influencers are starting to build their own platforms that aren't beholden to Amazon, Facebook, Twitter, Google, etc. But like with any kind of alternative outlet, it's going to be demonized by political opposition and corporate news. We're already seeing it with Substack, mainstream news outlets are already making moves to discredit the people who use Substack. I think the biggest thing will be if Democrats pursue legislation that categorizes "conservative" outlets as domestic terrorism. That seems pretty insane to do but I wouldn't be surprised if congress unveils that type of legislation during Biden's first term.
