IMO the problem is that a huge portion of America doesn't have the time, desire, or the smarts to suss out the actual truth- the 'do it themselves' portion of the statement. This comes especially at a time when MSM has essentially created so much static from discarded narratives and conflicting headlines that the truth takes time to pick out.
1. Possesses a brain with the ability to recall past events, analyze new information and draw conclusions.
Not everyone has the time to remember all the recent events going on, and voter attention span is very short. Does anyone remember how Pelosi tried stuffing airline emission standards into the Coronavirus stimulus bill? Will anyone remember how the Democrats intentionally torpedoed Tim Scott's police reform bill a few months from now? I bet even politically aware voters won't be able to completely remember what happened in the last few years except for the headlines, and Trump is at a disadvantage here as his accomplishments are buried in negative headlines.
2. Possesses two eyes to see the polling charts and what is happening in the country.
People (esp. Boomers) may still hold onto beliefs from long ago that polls are conducted by 'more knowledgable people'. Again, polls also offer enough room for people to squeeze their preconceptions into and rationalize.
3. Possesses two ears to hear what others are saying and the narratives being spun by the media.
People (esp. Boomers) may still hold onto beliefs from long ago that MSM is 'more informed' than the public. It also is very difficult breaking narrative trances, as it requires that you tell yourself that you're wrong, and to escape the walled garden and seek out countervailing facts (which themselves are intentionally hidden away). Secondly, we should be considering that voters will not have the entire picture at all times- they may miss out on MSM posting conflicting headlines, the actual truth in the body of the article, or MSM apologies/retractions.
Trump voters will seek the knowledge out themselves, but winning the election requires more than just core support. IMO, a talking head like Tucker is a necessary 'evil' in directly taking the message to the nonaligned voters, especially the moderates who don't pay that much attention to politics.
Possible tactic may be to target Black voters not primarily for their votes, but to dissuade them from being energized by the Democrats and to depress turnout. Trump needs to also energize his white voter base, especially the 'Blue Dog' working-class cohort he picked up in 2016 IMO.
Hispanics are going to be equally tough to get, but targeting long-time Hispanic communities like the Tejanos in Texas over recent migrants may work better. I think Asians may be a good sector to pick up, but younger Asians may be harder largely because they are primarily urban-dwellers, and went through the progressive educational pipeline (i.e. Sarah Jeong).
Yes, false-flag attacks should be 100% expected now as the protests lose their momentum. While most of the campaign is out of our hands, this is something where online users can actually have an impact.
It's Trump supporters' duties to discover the false flags and to spread the truth across social media to defuse progressive narratives- i.e. like how the Nascar hoax was quickly countered by the facts and photos.
