There are three practical reasons Trump does this:
- Deflection: Trump doesn’t have an affirmative platform. As a populist strongman, Trump’s platform is situational and entirely based on what his supporters want to hear in any given moment. If health care is in the news, Trump will say his plan is coming in two weeks (it won’t ever come). If immigration is in the news, Trump will say he will build a wall and get Mexico to pay for it (he won’t). But what’s even easier? Focusing on the shortcomings of the opponent’s platform. Any time this works, Trump saves himself an opportunity to be put under the microscope.
- Deflection: Manipulating the media works. Trump knows that the more ludicrous things he says about Kamala, even if the media then starts to talk about how he’s wrong or fact-check him, the focus is still on the thing he said rather than Kamala’s platform. It’s subtle, but it really does focus the media effectively on whatever he says, and use his frame of that issue as the media’s frame.
- Filling the echo chambers and other spaces. We’re in our own echo chambers like never before. Trump says these things so that the people in the right-wing echo chambers have a plausible response to Kamala’s policies, or even just need filler for their broadcast/websites/Facebook groups. Ultimately there is only so much media people can consume every day. If Trump has filled all relevant supporter spaces with his own opinions & framing, there is no time or energy left to explore other opinions and framing.
The “the economy was better under Trump” segment of voters is so depressing.
His policies were basically tariffs and random shiny object populist issues. His policies raised prices regressively while creating entire foreign industries that didn’t exist before that now price-anchor US products through his tariffs and trade restrictions, such as soybean. Blew up NAFTA just to replace it with an almost identical arrangement. He alienated our biggest allies and trade partners. He pushed down interest rates even when it wasn’t needed, ignoring the housing and stock bubble it created, because it made him look good.
It always reminds me how effective repeating a lie is - their “vibe” is that he’s some great businessman, and it’s enough to get their vote. They never check the sources for that “fact” (which are all Trump’s own self-aggrandizing statements).
