Given that Trump, in only four years, added just as much to the debt as either Bush or Obama did in 8 years each, I can't see a second Trump term that does anything to help. If he continues the economic policies from last time, I see the grand total being somewhere between $14-$16 billion between his first and second terms..
Both Bush and Obzma ended up adding around $7-$8 billion each. But Bush had to deal with the .com bubble bursting which fucked the economyand was gonna end up with a huge deficit either way, and several economy crises that were really his fault overall.
Obama inherited a recession and had the economy pretty healthy overall even. We recovered from the recession relatively quickly compared to other recessions like the one under Reagan.
Trump added about the same to the debt in half the time. The pandemic is partially to blame but he was already running at deficit so ranging from $2 trillion to as high as $5 trillion annually well before then.
I don't see Trump's economic policies changing. In fact, I forsee more corporations being given billions in subsidies, huge tax cuts with no significant spending cuts just like last time.
