When questioned, those who have/are voting for Trump in 2024 cite inflation, the economy, and immigration.
Trump inherited a surging economy coming back from the Great Recession. He did little other than sign into law the tax legislation passed by the Republican majority Congress. This cut top tax rates and raised taxes on those making $50K or less by $500/yr. That produced trillion-dollar Federal deficits while unemployment was ~3.5%. Inflation was lower, but he inherited that.
Inflation happened during the global recovery from the pandemic. Manufacturing, logistics, and supply took longer to recover than demand. This would have happened on Trump’s watch, but he failed in his bid for reelection. Neither he nor his opponent are going to impact the inflation that is already receding. Presidents don’t have as much power to effect change, and they need Congress to do much of anything.
The economy is actually pretty good. Employment, wages, and earnings are increasing, just not fast enough to overcome the surge in inflation caused by the interruption of global economic activity caused by the pandemic. Some of what Trump wants to do will disrupt the economy and hurt many of those voting for him, but, Congress. Even if he gets a Republican majority in both chambers, they don’t want to do what he wants to do.
Dealing with the Southern border is imperative, and, hopefully, Congress will act during the next term, giving the government resources it needs (much more than a wall). As for foreigners lacking documentation to be within our country, using a very old law to make massive deportations without process will definitely impact the economy, and initially, in a bad way.
Folks voting for Trump are really doing so because he makes them feel better about themselves. His opponent can’t penetrate that.
