Reasons why people voted for Biden in 2020
1. He was viewed as the "adult in the room" that would return dignity and normality to the office of President. That will no longer be a selling point for him.
2. Some felt that Trump was going to get us into a war with his 2am tweets. That also will no longer be a selling point for Biden.
3. Biden pushed a plan for a more humane treatment of immigrants that was better than Trump. His plan has been shown to be a total failure and the border will be a very big selling point for Trump, not Biden.
4. 2020 was the "summer of love" riots that were "mostly peaceful". Many thought that it was Trump who was stirring up strife in the country. Without a doubt that will be less of a selling point for Biden as Trump is doing very well with minorities, but if these riots for Palestine continue to increase we could have a whole new "summer of love" which could be a whole lot hotter than 2020 and would therefore become a very big selling point for Trump.
5. Bidens base was suburban moms. Interest rates at an all time high with high inflation, these are things that moms are acutely aware of. This will erode his support. Immigrants coming into these cities and taking up services are things moms also are aware of and the lack of safety is a third thing. Finally, the weaponization of the DOJ against Christians and especially parents at school board meetings is one more thing. All of these should erode Biden's support even if he still maintains an edge in this demographic, it will likely shrink from 2020.
6. Young people were enthused with the idea of getting their college loans paid off. It is doubtful this carrot will have as big an impact this time after seeing it not materialize over the last four years. But to make things worse what young people will be more concerned with is war. It is very possible that Biden will lose his advantage in this demographic.
7. The rules concerning mail in ballots heavily favored Democrats, unlikely that Republicans will be beaten that badly here this time.
8. CNN and MSNBC had an impact on the electorate in 2020, however their viewers and influence has shrunken in the last four years and it could be assumed their impact will also shrink.
9. Some people may have been apathetic and stayed home in 2020. Inflation, border security and war are three things that will motivate voters to turn out in mass. This turnout should favor Trump.
10. Democrats got billions in donations from FTX, money laundered that was sent to Ukraine. If we can keep from sending more money to Ukraine it could starve their campaign war chests and destroy many campaigns, so that not only does Trump win but many populist candidates also win, doubling or even tripling the impact of the "crazy 8" led by Matt Gaetz and give the Senate to the Republicans as well.
