The explanation of why Harris had nothing to do with high inflation which was global and could go on for a long time the reasons. No President caused it and no President can bring down the huge increase of the past in prices in a free enterprise economy based on supply vs demand. Many food prices are determined by global pricing of commodities on the board of trade etc. The FED slowed the out of control hot COVID economy to tame inflation which is now close to the 2% target both in the US and most Western countries.
Further, the role of the VP is to support the role of the President, not make her own
Of course, she supports the great Biden boom economy with some of the lowest unemployment in history. This economy beats all other major economies in GDP growth except China (which has other major issues and is not used to only 8% growth) and Russia, which is fueled by war spending but is expected to drop in 2025. Most of Europe is in or near recession vs the US avoiding it seems even a soft landing with our strong economy even with high interest rates to slow our roaring Biden economy. It is not all due to him but certainly nothing to do with Trump whose policies would stimulate more inflation (including tax cuts for the wealthy and broad tariffs, which are like sales taxes to consumers)
The major Biden spending has been in investments for clean energy, tech manufacturing in the US vs China and so many other good investments for the future and during the COVID payments to avoid poverty and needy folks who could not work. Vs. Trump mess of just tossing out checks to anyone and delayed one big one since he insisted on having his name on it.
You can not provide a comprehensive factual answer in a 1-minute limit in the debate stating facts, not the constant string of lies from Trump and his madness, childish name calling for anyone against him and his goal of creating chaos so he can be the strongman dictators he wants to duplicate such as Putin and his love of N Korea, Oberon etc. And, of course, he is following the path of Hitler closely in his con-man misinformation for the sake of power regardless of facts.
